The process took 2 days. I interviewed at AMD (Austin, TX) in Mar 2011
Interview
The interview lasted about an hour, and I was interviewed for half an hour by each interviewer. I was asked technical question relating to transistor cross sections and logic design. It was a fairly laid back interview and the questions were only moderately difficult at times.
In addition to the technical questions, I was asked how I would describe a transistor to someone with no engineering background. This was aimed at testing communication skills as well as creativity.
Interview questions [1]
Question 1
How would you change this CMOS inverter to either reduce leakage or decrease delay?
I applied through college or university. The process took 3 weeks. I interviewed at AMD (Austin, TX) in Jan 2011
Interview
Telephonic as well as 5 1:1 onsite interviews were pretty straight forward. Questions were nice with varied difficulty level. It included Computer Architecture, Verilog, C, Perl and general behavioral questions.
