I applied through college or university and interviewed at Qualcomm.

Interview Details – Obtained an interview through campus recruiting. It consisted of an hour and a half phone interview which started out with going through the resume and then led to several technical questions as a follow-on. After this, there was a day long on-site interview, starting with a 1hr presentation to a team of 8 people, followed by 1-1 sessions with several engineers.

Very Difficult Interview

Design Engineer Interview

Design Engineer
San Diego, CA

The process took 2 weeks - interviewed at Qualcomm in January 2011.

Interview Details – The people setting up the interview were very nice and courteous. The interview was highly technical and concentrated on expert level questions. The posted job was not for a principal or senior level engineer, but they were obviously looking for someone with that kind of experience. The interviewer had a condescending attitude when you didn't know the answer and would not have been a good person to work for. Someone mentioned that the PhDs at Qualcomm look down on people who don't have one and my experience supports that claim.

Interview Question – What is the equation for device mismatch?   Answer Question

Design Engineer Interview

Design Engineer

I applied through college or university and the process took a day - interviewed at Qualcomm in August 2013.

Interview Details – It was through campus recruitment. They had two technical rounds. I cleared the first roud but was rejected in the second. In the first round they asked questions based on Finite State Machines. Also a simple digital circuit and it's truth table. Also I was asked to design an N-MOS inverter. There was also a puzzle - if there are 21 balls with only one weighing heavier, how will you find it using only one weighing balance in the minimum number of weighings?
In my second round I was asked to design the FSM for a Vending Machine. And then they asked me to solve a timing analysis question which I couldn't. It was a little complex involving setup and hold time.

Interview Question – The digital timing analysis question.   Answer Question
