First-hand accounts from people who interviewed at Qualcomm.
Engineering Intern
Got the opportunity through campus placements. They skipped any Online Assessment and went straight for a direct interview. There were 3 interviewers. First, they asked me about the projects and internship I listed on my resume. Then, they threw in some basic to medium-level questions about ML, DL, and NLP. They also asked about data structures and gave me a coding problem to test my logical thinking.
- What are your strategies for dealing with imbalanced classes in a dataset?
Engineering Intern
The interview will mostly cover technical stuff about camera sensors and the Image Signal Processor (ISP) pipeline. You gotta be ready to really talk about what you know about camera sensor tech, the different parts of an ISP, and how the whole image processing thing works from start to finish. It's gonna be super important to show you know about stuff like sensor types, pixel tech, how to reduce noise, color processing, and making images look better. They'll also want to hear about your past work, especially any internships you've done that are on your resume. Make sure you can explain what you did in those internships and how you used your tech skills in real jobs. Talk about tough projects, how you solved problems, and what you did for the team or company. Oh, and there will be behavioral questions too, to see how you handle things like teamwork, talking to people, adjusting to stuff, and solving problems. It's a good idea to have some stories ready that show you're good at these things, whether from school or work. So yeah, it's a mix of technical questions on camera sensors and ISPs, digging into your internship experiences to see your practical skills, and behavioral questions to check out your people skills and problem-solving. Be ready to show you're a good fit for the job.
- Is there anything about your project that could have been done better?
- Can you tell me about your understanding of camera sensors and the ISP pipeline?
- What do you know about different sensor types, pixel technologies, noise reduction, color processing, and image enhancement?
Engineering Intern
So the interview started with intros, then he asked me to explain what a constructor is and to code one. After that, he wanted me to write a program to check if a super large number, one that wouldn't even fit in a long long, is divisible by 2. We chatted a bit about that, and then he moved on to my project, asking some basic questions and then some questions related to the code. The whole thing was about 30 minutes.
- Can you define a constructor and provide a code example?
- Please write code to check if an extremely large number, too big for even a long long, is divisible by 2, aiming for an optimized solution.
