Validation Engineer Interview

Anonymous Interview Candidate
San Jose, CA

I applied online and the process took a day - interviewed at Dolphin Technology Inc in July 2012.

Interview Details – Interviewed for a position of Junior level Validation engineer at their San Jose office.
Interviewers were fresh graduates with less than a year's experience and I was interviewing for a position that required 2 years experience.
The same interviewer got mad at me because I would need H1B sponsorship while my name in my resume had made him think I would not ! (BTW He himself was Indian and was on a H1!)
Interview was extremely un-organised and one of the interviewer got kind of offended because he could not understand my PERL program using Regular expressions.
After the first 2 rounds, they had me wait for around 25 mins for the next interviewer, who came in only after I asked the receptionist about it.
I was not too unhappy to have not heard back from them ..

Interview Question – Write a PERL script to find a certain key word in a text file.
Solid state electronics questions.
Questions about latches and flipflops
Basic VERILOG coding questions.
Basic C coding questions - (Write a function that accepts 3 numbers and returns the highest 2- this was one of the best questions in the interview, asked by a more experienced engineer)
