Engineering Interview

Engineering
San Diego, CA

I applied through an employee referral and the process took a day - interviewed at Qualcomm in July 2011.

Interview Details – Initial phone interview was very basic and relatively short (30 mins). Questions ranged from basic EE 101 type to synthesis issues. It was NOT by the hiring manager but another engineers in the hiring team.

Interview Question – Setup and hold time questions. Add inverters on the clock path, etc.   View Answer

Negotiation Details – My staffing specialist didn't try to really negotiate. I knew what QC had offered another candidate a week before with identical qualifications and job description. When asked, the high end of the salary for the staff engineer, she said it was way above and quoted $30k less. I asked about benefits, etc., and said in between the two numbers was acceptable.

Engineer Interview

I applied online and the process took 2 weeks - interviewed at Qualcomm in June 2011.

Interview Details – Was contacted and asked to meet one person. Subsequently went in spent most of a day meeting 5 people.

Their interview process seems to be structured for someone who is not very senior. They ask a lot of very basic questions on digital design, DSP, communications.

 Found that most of the interviewers had a lot less experience and so their perspective is very limited. Out of the 6 people met, in total three seemed to adapt to the level of the person being interviewed while the others stuck to the type of questioning for a mid to junior level person and not the type of interview someone with more than 2 decades of experience would expect. Some of them did not seem to understand the topics they were asking questions on and failed to understand things when alternate solutions were proposed or it was pointed out what they were saying is incorrect.. Sent one of them excerpts from text books subsequently.

For a senior person, I woud have expected them to discuss past work experience, and get into technical discussions of past projects and how it relates to what they do, chip architecture, etc. They stuck to mostly simple questions such as synchronization, FIFOS, state machines, C syntax, PERL syntax, etc. Only two or three of them seemed to a have broader perspective, the rest seemed to be run of the mill with no idea as to how conduct a proper interview.

Engineer Interview

Engineer
Raleigh, NC

I applied online and the process took 2 days - interviewed at Qualcomm in January 2010.

Interview Details – Received a phone call to schedule a phone interview. Then received a phone call with 2-3 engineers and answered some technical questions. Subsequently scheduled an on-site interview.

There were 4 sessions each about an hour with 2-3 people. Questions about micro-architecture and logic design were asked. Variable-width adder, pipeline control, cache configuration, multiplier, etc.

Interview Question – Design a variable data-width parallel adder that can optionally be signed or cosigned using a minimal number of bits.   View Answer

Negotiation Details – I was able to negotiate but decided not to. The process of getting an offer through the hiring system is rather long (2 weeks) so negotiations would take a while. My advice is to ask for a higher number than you'd be willing to settle for in the first place.
