Very Difficult Interview

Senior Software Engineer - Embedded Interview

Anonymous Interview Candidate
San Francisco, CA

I applied through a staffing agency and the process took 4 weeks - interviewed at Cryptography Research in March 2009.

Interview Details – I was approached by a head-hunter about a job with this company. It seems like a very HOT job, it pretty much had everything I was looking for (even though I'd have to move to SF, but oh well).

BEFORE I could talk to anyone I had to write a C program of significance, and busted tail all weekend on it.
Then came the phone-screen (or two...I forget). It seemed to go very well.
Interview Day: I dressed up sharp for the meeting, and felt ready for their questions. Boy, was I fooled!
It was a very technical interview overall.

Got asked 2 tough C questions, had to explain the totality of the SW appliance I was working on.
During the interview I got the sense no one really liked me, that they wanted to prove they were THAT much better than I was. I got that impression after their VP asks me a question about audio digital fingerprinting (totally outside my element at the time).

I didn't get the job in the end, but I was told I've gone through their process MUCH further than anyone else had at the time. This company also taught me to move on after the interview is done, and following up with a company that doesn't want you is simply pointless.
