Hardware Test Engineer at Qualcomm
No Offer – Interviewed in San Diego, CA – Reviewed Jun 3, 2013
Interview Details –
Received the onsite interview request after the phone interview. The onsite process includes 6 rounds.
Technical interviewers were easy going, they would give you hints or lead you if you have no clue. Asked about hardware test related questions, include what to test, how to test, what could be reasons if result is not as expected. Require basic knowledge about circuit schematic diagram, wireless communication transceiver diagram, noise figure, link budget calculation, sensitivity, testing equipment (e.g. VNA, Spectrum analyzer, etc.), basic C++ or C#
HR interview was very nice, introduced the company and its benefits, very few behavior questions.

IT Manager at Qualcomm
No Offer – Interviewed in San Diego, CA Apr 2013 – Reviewed May 23, 2013
Interview Details –
I initially had a group phone interview that lasted about 10 minutes until I was passed on to next stage. At my in-person interview, I first met with an HR person and went over some basic info. I then met with a panel of four supervisors. Lots of questions about my resume, but the interview felt unstructured and ad-hoc with lots of silences. One of the interviewers seemed like he was upset - he barely made eye contact with me. Odd experience.
Once the interview concluded, one of the managers walked me out and said that I would be brought back in for another panel interview, but I never heard from them again. Surprisingly unprofessional from a company this large.

Embedded Software Engineer at Qualcomm
No Offer – Interviewed in Apr 2013 – Reviewed May 21, 2013
Interview Details –
Phone Interview : Pretty much standard questions about static keyword, Linked Lists and then finally the interviewer showed me few pieces of code on google docs and asked to find problems in them if any like Memory leaks. Segfaults etc. Later, I found out that the questions were picked up from some website word-to-word. I gave answers to almost all the questions but failed to notice problems well in the last two pieces of code. It's ridiculous, that it was the basis of rejection.
Also, the interviewer kept boasting about how he has worked in almost all the areas that I can possibly name. I am not saying mine was a stellar performance, but overall negative attitude by interviewer and Negative interview.
