    Computer Vision Algorithms Expert Interview

    Anonymous Employee in Santa Clara, CA
    Accepted Offer
    Positive Experience
    Difficult Interview

    Application

    I applied through an employee referral. The process took 8 weeks. I interviewed at Qualcomm (Santa Clara, CA) in December 2012.

    Interview

    A two stage process starting from the phone conversation. I had a medical device prototype which was reviewed by the principals which ultimately demonstrated a working knowledge of optics. This simplified the process and led to the personal interview. The final phase was a multi-phase event that include an intensive discussion during the lunch. Individual meetings preceded and followed. Lunch interview included a meeting with a world class optical consultant visiting the site.

    Interview Questions

    • The position was of a senior technical consultant that aided the team in delivering a sequence of prototypes based on new technologies. Although this full-time position lasted over 2.5 years it was from the very beginning a good understanding about a tentative nature of this arrangement. Most of the questions were very technology specific. One must also understand that IP was being filed so no direct questions were asked due to the sensitivity of the legal process in progress.

      So typical questions in this category are:

      1. Given the physical principle used, can (my) device be expandable to larger format?
      2. How this can be compared to the work done by so and so?
      3. Were I involved in standard committees? (yes)
      4. Possible applications for the physical effect xyz?
      5. Issues in software implementation of the application function that is based the principle under discussion?   Answer Question

    Positive Experience
    Difficult Interview

    Application

    I applied through an employee referral. The process took 6+ weeks. I interviewed at Qualcomm (Santa Clara, CA).

    Interview

    I applied online and had an in-person recommendation from someone who works at the company. They emailed me to do 2 rounds of technical phone interviews. The interviewers were really nice and helpful. The interviews were about the courses I took in graduate school (I am on my way to PhD by the way), about Probability, Detection/Estimation Theory, Wireless Communications and Signals and Systems. Most were basic things, like definitions of simple things like fading, stability of a filter and so on. I was asked to do some computations on detection in Gaussian channel like error probabilities and detection regions. I was also asked some brain teasers like coin weighing problems. Then I was asked to do an additional third round of interview with similar problems. All the interviewers were nice and helpful.

    Interview Questions

    • I more or less knew what the interview would be like, so there was no unexpected question. I guess the problem I had the most difficulty was the brainteaser, a coin weighing problem with faulty coins. You have N coins out of which one is heavier. How many uses of the scale do you need to find it? The second part, now you don't know if it is heavier or lighter. How many uses of the scale do you now need to do? Then you need to relate this to a problem in information and coding theory.   1 Answer

    Negotiation

    Since this is an internship, I don't think you can negotiate much. I just took the offer they gave me and the pay is pretty competitive.

    Intern Interview

    Positive Experience
    Difficult Interview

    Application

    I applied through college or university. The process took 5 weeks. I interviewed at Qualcomm (Santa Clara, CA) in October 2011.

    Interview

    Talked to the recruiters and handed in my CV during their visit to our school. After two weeks, I got the phone interview invitation. They asked me what time I'd like to be interviewed. I asked to be interviewed two weeks later.

    There were two interviewers. Each of them interviewed me for about 30 minutes. After a brief introduction, they asked me to grab a paper and a pen, and write down the problem and some equations. They also asked me to derive some results, and explain how I got the solution. There was a bit of calculations; not really hard, it's more about the basic concept. But it's not easy to answer if you are not familiar with the topic.

    The first interviewer asked all technical questions. The second interviewer spent half of the time chatting with me and half of the time asking technical questions. Before ending the conversation, they asked me if I have any questions. I seized the chance to chat with them about their work and the working environment. Although I didn't get the right answer to all of the questions, the overall conversation was quite smooth.

    In about a week I got an email form the recruiter telling me I was accepted.

    Interview Questions

    • One interviewer asked me an information theory puzzle. I never heard of such a problem and didn't know how to answer it. I asked for hints and the interviewer guided me to find the answer. It seems to be OK if you don't know how to answer the question at first. Ask for help and try to tell them how you think.   Answer Question

    Difficult Interview

    Application

    I applied online. The process took 2 weeks. I interviewed at Qualcomm (Santa Clara, CA) in April 2013.

    Interview

    One phone interview and then onsite interview. First I gave a presentation on my thesis onsite. Several difficult questions were asked during my presentation. Next, seven (1:1) interviews. I really enjoyed the interview process. I guess they are looking for: 1) Skill set -- how it matches to their projects, 2) Motivation and Passion towards the projects, and 3) Team Player: how well you mingle with the team members.

    Interview Questions

    • How well your ideas (thesis) fit into Qualcomm research projects? I think that this is really very difficult question to answer.   Answer Question
