    Senior Network Integration and Optimization Engineer Interview

    Anonymous Interview Candidate in San Diego, CA
    No Offer
    Negative Experience
    Difficult Interview

    Application

    I applied through other source. The process took 7 weeks. I interviewed at Qualcomm (San Diego, CA) in July 2016.

    Interview

    Send resume via surface male. Took 4 weeks to get phone interview. HR specified 4 different parsons to interview for 30 minutes during the week. 5th person contacted without HR approval and requested an interview. During an interview process I found that the actual position is not exist. They are just looking for talents. It was a waste of my time. I also found that Engineering jobs were outsourced to China and a lot of American employees were effected by layoff.

    Embedded Software Engineer Interview

    Anonymous Interview Candidate in San Diego, CA

    Neutral Experience
    Difficult Interview

    Application

    I applied through an employee referral. I interviewed at Qualcomm (San Diego, CA) in July 2016.

    Interview

    I was referred by an employee at Qualcomm for Linux audio team. Was scheduled a phone interview. The interviewer did not call at the mentioned time. He later re-scheduled the interview for next day after I have waited for almost 8 hours for him to call. The interview was for 45 minutes. Mainly covered few HR questions like what is your background? Have you worked in the past? What are your strengths? Rate yourself in C, C++. Later he has jumped into C questions. Very depth analysis required. Each answer has to be explained with the help of examples. And must know the differences between different things and which to use when. After C , he asked few questions about just basics in C++ because I have told him I have never used C++. And later the questions were about Embedded Systems and finally a brain teaser for 5 min. I could only answer the basic definitions but I have no in depth knowledge on the subject which is why I got a reject. They would want an experienced candidate because they would know the actual implementation with examples.

    Antenna Engineer Interview

    Anonymous Interview Candidate

    Negative Experience
    Difficult Interview

    Application

    I applied online. The process took 2 weeks. I interviewed at Qualcomm in June 2016.

    Interview

    I applied online and got a call in two weeks. The first interview was a phone interview. It well really really well.The person appreciated me and said I was excellent and would call me for an onsite interview. But next week instead of onsite interview I had another phone interview. Its not something common with Qualcomm to conduct two phone interviews and I was pretty doubtful about that as there was no reason for the second phone interview when they already tested the required skills well in my first interview.Then I read glassdoor reviews about the company. A person had explained a similar experience just that they called him/her onsite and eliminated on purpose as they wanted chineese/korean only to be there.

    The second phone interview was such a stupid interview. The person was asking all the stupid questions in the world to eliminate me. I can also do that to him -ask unusual questions nobody would even think of and eliminate. How stupid could have he been to talk about industrial experience for an hour when he knew I had only six months of experience.I still regret that I should have told him directly that I know the reason why you conducting this interview. LOL btw they could have done a better job instead of being so obvious about your racism/ any other reason to reject. Hope they do not make it obvious next time.

    My only concern is in such a big company how does anybody from higher management not look into such things and that it is infested with chineese/koreans whatever I am not sure. Me not getting the job isn't my problem. But they what they did the whole thing wasting my time makes me really frustrated. For those who read this, if you had a similar experience please do write reviews so someday they stop doing this.I was really shocked by their way of handling it.Silly and mean.That's all I can say.

    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
