Summer Spotlight - Qualcomm

This week we are talking with Mario about his experience so far at Qualcomm

Aaroh Mankad

About Me

I’m a Senior Computer Science student at UCR. I am the Outreach Director for Cyber@UCR, an Undergraduate Researcher at M.A.D. Lab with Dr. Papalexakis and a Google Scholar. I grew up in the Bay Area (South Bay) and I transferred to UC Riverside in Fall 2016 from De Anza College (Cupertino, CA). I started my academic career as a Business student at De Anza College in Cupertino, California. Business was fine, but I didn’t feel challenged so I switched to Computer Science and I graduated with an Associate’s in Business Administration and coursework towards Computer Science.

Interview Process

The interview process for Qualcomm is 2 separate 45 minute phone interviews (back-to-back) with members of the technical team, which includes questions about your resume, design questions that are very in-depth and sometimes coding questions. In my first phone interview I was asked some soft skills questions and then I had a barrage of operating systems questions to ensure that I understood every aspect of an operating system. A few things I was asked about is context switching, threads vs. processes and virtual memory. In my second interview, I was asked to design a communication system between employees at a company. Throughout the entire interview you're asked to explain further with everything that you talk about. The main purpose of the questions isn't so that you can just answer correctly or hear your thought process. The main purpose is to find out what you know and how much you know. So if you find an opportunity to explain a component that you know very well, feel free to do it because it'll showcase your depth!

BTW, the pay is very generous and they pay for your housing and utilities in San Diego! Got a family? They give you a stipend to cover rent!

Memorable Experience(s)

My most memorable experience was going on a “booze cruise” with my team at QCSS. We went on a scavenger hunt cruise to Coronado where we had mimosas as we sailed through the waters while getting paid for it. I also enjoyed going to the San Diego fair throughout the summer and visiting the beaches. Qualcomm’s hackathon (Hack Mobile) was fun because we were able to work with Qualcomm DragonBoards and there were many surprise events throughout the night. Qualcomm has a weekly BeerQuest where interns try a new brewery every week! The intern favorite is usually a flight (3-4 beer sampler). We also have a weekly Sushi & Sake night, which mainly just consists of sake… and a headache the next day. San Diego is full of alcohol as you can see. Qualcomm interns like to… ( )code ( )eat ( )sleep (x)drink alcohol. We also had an entire day of volunteering that Qualcomm paid for. I learned how to make a dog toys for animals in shelters, others when to a river cleanup and there were a few other volunteer events. I missed a chunk of intern events this year because I was out for two weeks so I missed Qualcomm’s walk at Pride. A lot of interns say that walking with the Qualcomm float and meeting Steve Mollenkopf at pride was a fun experience.


My first day at QCSS there was a retirement party and I had a beer (3 actually) with my mentor, manager and fellow interns...

The culture varies by group as with a lot of companies. In QCSS in particular, we are a close-knit group with a small business feel, but we have the resources of a large company. In QCSS you get to work on every aspect of Qualcomm since you are assigned to project teams that varies from anything in the disciplines of Electrical Engineering, Computer Engineering and Computer Science. Oh, and we also have an epic snack table!

Qualcomm has sparkling water (La Croix and Bubbly) and soda fully stocked throughout the entire campus for its employees. The company is very focused on innovation so the employee search portal (QPeople) showcases employee patents (the CEO has roughly 40!).


At QCSS, I was given an office and a lab bench, but most of the interns usually work in the lab since we’re all next to each other and we can bounce ideas off of each other. I was issued a Windows laptop (a lot of IoT device tools that we use requires Windows) and I was issued a Linux desktop with a triple-monitor setup.

For my project, I’m working on a proof of concept with a few of our newest technologies on the MDM9206 IoT device. I have worked on many different levels of our technology ranging from assembly and C to Java and Python. Areas that I have been able to explore is mobile networks, RF, SIM cards, modems, SoC, CaaS, TrustZone and ThreadX to name a few. QCSS has a lot to offer for a new grads/students since it is structured into project teams for contracts so you get the opportunity to learn a lot and use all of Qualcomm’s technology.

In QCSS, our intern presentations are done in a lecture room in front of fellow interns, staff/senior engineers and executives. Other groups in Qualcomm have intern presentations and/or poster presentations.


Qualcomm is located in San Diego, California. There is an abundance of things to do in San Diego on any given day. My favorite place to go for nightlife is Gaslamp and Pacific Beach, beaches at Del Mar and Ocean Beach, great food in Convoy and tacos in Chula Vista, and great sunset view at Gliderport. Simply said, you won’t run out of things to do. My favorite thing to do was to go on bike rides and hikes around the trails in San Diego and watch the sunset at Gliderport or Seagrove Park! And OF COURSE the tacos at Tacos El Gordo!

There were so many photos we had to pick the best ones! See the full photo album here For referral:





Summer Spotlight - MacREU

This week we are talking with Mina about her experience so far at MacREU

Aaroh Mankad


Hello! I'm Carmina Jean delos Santos, but people just call me Mina. I'm an incoming second year Computer Engineering major. My technical interests include VLSI and embedded systems. This summer, I have been working as a microelectronics research fellow, under the Materials Connection Research Experience for Undergraduate Students (MacREU) program. The program funds my project, which revolves around chip optimization.

Interview Process

I have been working in Dr. Bartels’s research lab since Winter Quarter, and he recommended me to the program.

Culture & Work Life

The program itself is very initiative-based; there is no determined schedule. MacREU aims to emulate life as a graduate student, conducting your own experiment and obtaining results for your own project. At the end of the program, we are to present our findings at a research symposium.


My project is “Transition Metal Dichalcogenide (TMD) Integrated Waveguides for Optical On-Chip and Inter-Chip Communication.

To preface, TMDs are 2D semiconductors. They are widely studied as a replacement for Silicon, which is no longer semiconducting at a certain width. The integration of TMDs in microelectronics would allow us to go even smaller with our computing hardware.

Instead of transmitting data using copper wires, we want to use optical waveguides lined with a TMD. Think of it as fiber optics on the nanoscale.

Using TMD integrated waveguides instead of copper wires, we escape a lot of copper wire’s flaws, which involve data loss and the inability go smaller. Additionally, because light has different wavelengths/a larger bandwidth, this opens up to a future of quantum computing, should.


MacREU is hosted on the UCR campus, and my lab is in Pierce Hall. Even though it’s a little too familiar of a place to be, especially during summer, I like that I run into a lot of my friends taking summer courses or working in the area.

I primarily work in Pierce Hall and in the Cleanroom.

Summer Spotlight - Informatica

This week we are talking with Will and Patrick about their experiences so far at Informatica.

Informatica is a world leader in Enterprise Cloud Data Management. Informatica develops various products related in Big Data, Cloud Services, and all things Data (Integration, Quality, Security, and Management). Its products are used by all of the Fortune 10 companies and 85 of the Fortune 100.


William: My name is William Shiao and I am a computer science major about to start my third year this fall. My interests within computer science are in machine learning, algorithms, security and web development. I am interning as a Software Engineering Intern on the Secure@Source team, whose product helps companies find and secure their sensitive data.

Patrick: Hi! My name is Patrick Le and I am an incoming senior majoring in Computer Science. My interest lies in full stack web development and product management. At Informatica, I am a Software Engineer for their Cloud Services division.

Interview Process

William: I applied for the position through LinkedIn at the end of November and received a HackerRank test. I then did a technical phone interview with a software engineer on the team followed by a behavioral interview with the team’s manager. I received the offer in February.

Patrick: I applied for the Software Engineer Intern position in early January. Here is the timeline…

Culture & Work Life William: I like the culture at Informatica—the people are very helpful and friendly. The atmosphere is also fairly relaxed and the hours are flexible, with many employees working from home on Fridays.

The company’s values are DATA, which stands for “Do Good, Act as One Team, Think Customer-First, and Aspire For The Future”. The values are repeated often and provides a good idea of what the company is about.

There are also several events for the interns, like going to a Giants game and volunteering at Habitat For Humanity. The company also has some cool events, like an annual trip to Lake Tahoe in early September.

Imgur Will's Desk at Informatica

Patrick: There is always something to do at Informatica. The company sponsors several outing events such as intercompany sporting competitions, volunteering events, and team-based socials. We have team meetings and one-on-ones with our manager once every week. Everyone is really smart and will provide you with a lot of feedback/advice.

The company as a whole cares deeply about their employees. Informatica is a privately traded company, but the leadership is very transparent about our quarterly earnings and product roadmap. There are two exits for Informatica. Either get acquired or go public.

In terms of amenities, all employees receives free gym passes at Pacific Shores and reimbursed work travel (limited to public transit). We also have free drinks (soda, sparkling water, etc) and snacks (beef jerky, chips, etc). Fun fact, I have drank 157 Diet Cokes, 26 Dr. Peppers and 13 Brisk since the start of my internship to this spotlight.

Overall, I am enjoying my time at Informatica and making the most out of it!

Btw, we all get an adjustable standing desk :)

Imgur Patrick's Desk at Informatica


William: During the first week, my team was busy with internal planning meetings so I was given a task to improve the performance of a specific feature.

Then, I was assigned my first project, which was creating a plan and proof-of-concept for a microservice deployment of part of my team’s product—first on AWS, and then on our internal platform, IICS (Informatica Intelligent Cloud Services). I learned a lot about the various offerings of AWS, as well as how to architect and deploy a microservice-based application.

After that, I was given a project to create an internal application for my team. I got to learn a lot about the field of NLP (Natural Language Processing) and apply many of the the techniques I learned from CS 235 (Data Mining) on a real project. I also got the chance to use my technologies of choice, like Node.js and Python.

I plan to finish that project soon and will be able to start a third project, which is still to be decided.

Patrick: Unfortunately, my project is confidential, but the project will soon be in production.


William: We are interning at Informatica’s Redwood City location, which is in the Pacific Shores Center. It has a great view of the bay, as well as a softball field, beach volleyball court, basketball court, and gym. The office itself is also very nice, with plenty of free drinks and snacks.

Informatica provided housing, so Patrick and I are staying near downtown Redwood city. The weather is awesome and there is plenty to do at night with a lot of restaurants and a movie theater within a ten minute walk. We are also staying within walking distance of a Caltrain station, which allows us to conveniently travel around the Bay Area

Patrick: I work at Informatica’s headquarters in Redwood City. Pacific Shores is a community of companies on the outskirts of Redwood City. We own two large buildings at Pacific Shores. The community is very picturesque and peaceful. I often walk around the campus during my free time.

The buildings are amazing. There are Game/Lounge rooms, cafes, and LOTS of meeting rooms (with whiteboards).

Summer Spotlight - Esri

This week we are talking with Patrick, Sid, and Elijah about their experiences so far at Esri.

Esri is the global market leader in GIS (Geographic Information Systems). Esri develops ArcGIS, the most popular mapping and spatial analytics software.

Cafeteria Stairs


Patrick Patrick - I’m Patrick Tumbucon, and I’m an incoming senior majoring in Computer Engineering. My technical passion is front end web development, but I also enjoy back end development and web design. At Esri, I’m interning with the Search Engine Optimization team.

Sid Sid - My name is Siddharth Menon. I am a Computer Science major, entering my senior year in the fall. My interests lie in machine learning, computer vision, and computer graphics. At ESRI, I am interning with the team at the Applications Prototype Lab (APL).

Elijah - My name is Elijah Cain, and I’m pursuing a B.S. in Computer Science. I’m a capable full stack developer with emphasis on backend development. I am on the ArcGIS Enterprise software development team.

Interview Process

Patrick - I was contacted by two teams: The SEO team and the JavaScript API team. I followed through both interview processes concurrently. Each one started with a behavioral/conversational phone call, then the SEO interviewer (who is now my awesome mentor) asked a few basic technical SEO questions. I received an offer from the SEO team about a week later. I was offered an onsite interview with the JavaScript API team, but I declined due to my heavy workload at the time, among other things.

Sid - I was interviewed twice. The first time was by an HR representative. A few weeks later, I got an official phone interview with the APL team. I was asked about the projects I had worked on, my technical interests, as well as my experience using different frameworks and languages.

Elijah - I had an initial HR screen where I talked about my development interests and skills. I then had a 1-hour technical interview with my current team mentor. We used a shared online coding editor and he asked me basic data structure and algorithms questions as well as some C++ specific questions.

Work Life

Work Station Hackathon Presentation Patrick - Search engine optimization falls within marketing, so my desk was placed along with the social media team (who are all very fun and animated people!). My mentor is fully aware of my developer background, so she encourages me to work on the more technical parts of search engine optimization. For example, I’m currently spearheading a project that implements JSON-LD structured data across our thousands of web pages. This will help boost our search rankings and populate the SERP with rich search snippets.

Working in the marketing department as a developer has been more fulfilling than I ever thought it would be. Not only can I create a product, but I can polish it in such a way that makes it attractive to use. This proved to be a very useful skill for the intern hackathon, where I led my team to earn 2nd place.

The intern coordinators take their job seriously, and they have made the intern experience very enjoyable. The highlight of the intern events was 100% the intern hackathon.

Esri is a unique company in many different ways:

  • There is a very flat hierarchy in the context of leadership, and I haven’t met anyone with a sliver of an ego. I would schedule meetings with people like the head of branding, the VP of marketing, and the front end development team lead just to have casual conversations about our passions and experiences. Heck, even the CEO eats in the same cafe as every other employee.
  • Every employee gets paid hourly. This can be a good or bad thing.
  • Esri is privately owned, so the company can freely develop their products without having to listen to shareholders.

2018 Interns Sid - While I can’t speak about the details surrounding the project I’m working on, I can say that many of the skills that I have developed through hackathons and my previous courses (like CS 171/170/130/etc.) have come in handy to get things done. I have been working with machine learning/deep learning frameworks (such as Tensorflow and MxNet) and the team has been actively working with me to get the project done.

Additionally, the internship coordinators always have some fun activities planned for the interns throughout the summer. The biggest highlight so far has definitely been the intern hackathon.

Elijah - I’m doing server-side development for the ArcGIS Enterprise software platform. More specifically, I’m working on export tools that allow users to export different types of services that are supported by ArcGIS. I’m also using JUnit to write regression tests in Java to make sure my code does not disturb any of the surrounding functionality.

I participated in the Esri hackathon and was on one of the finalist teams. There are a lot of intern activities and career workshops. The work environment is very laid back and collaborative.


Laptop Outside Patrick - It’s hot. It’s pretty much Riverside weather, to be honest. But there are some awesome food places in the surrounding area, such as Eureka Burger and the Gourmet Pizza Shoppe. I commute from Riverside with other interns, so it’s a bit harder to hang out with the interns who live in Redlands, but we make it work.

Sid - Downtown Redlands, a 20-minute walk from the ESRI campus, is definitely a cool place to go to with some really good food to look forward to.

Elijah - The Esri campus is very unique and Redlands has some cool spots too.

Final Remarks

Plants Patrick - Esri is the unsung hero of tech. I can’t immediately name a tech company that has such a positive, global impact on the world like Esri does. Esri powers the real-time maps of 911 first responders and continually makes breakthroughs in education, conservation, and sustainability of the environment. If you want to make a difference in the world, Esri is the place to be.

Esri looks for excited and passionate candidates who are eternal students (figuratively, not literally). If you’re interested in working here, please don’t hesitate to contact me at and I can help you out.

Sid - Being a part of the Applications Prototype Lab has allowed me to be able to play around with some cool new technologies and the overall experience so far has been great!

Elijah - Esri is a fantastic company to work for. Leadership has a great vision for the company and it trickles down to all of the employees. The developers are high caliber, but very down to earth and collaborative.

Memorable Experience


AT&T had a day call “Intern Day of Impact” for interns across the world. For the El Segundo interns, we volunteered at the Los Angeles Food Shelter for a day. By the end of the day, we helped prepare 8,645 lbs of food for people with food insecurities.




GitHub supports events all across the world. One event I got to help out was Battle Snake 2018 which is an AI competition for over 450 people to build AIs for the game snake. This year’s competition was hosted in Victoria, British Columbia, Canada.

Sponsors of the events create Challenge Snakes which then the participant’s snakes have to challenge. For GitHub, I built a snake using Python and a full-time engineer built one using Ruby. Our challenge for participants was a 2 vs 2 but it would be our 2 different snakes with different heuristics vs 2 copies of the participant’s snake.



Imgur I can’t say much about my project without revealing the secret sauce. I can say however that taking CS171 (Data Mining & Machine Learning) before my internship helped out a ton. I am working with big data systems (Apache Kafka, Apache Hive, Hadoop) and using machine learning (XGBoost, Tensorflow). This isn’t the typical “give an intern something to do” project as the direct report for it is the CTO with over 40 full time staff working on it.



Imgur AT&T is located in El Segundo, CA with housing provided in Playa Del Rey. It’s an amazing location by being a part of Los Angeles and being right at the beach. There’s tons of things to do from beach-going, hikes, and eating amazing food. Imgur The work environment is one of my favorite parts. It’s an open space layout so inter and intra-team interactions is always happening. We also have the occasional ping pong tournament happening.
