I had previously worked for the the company. Therefore, the interview was setup via a friend who was still at the company. The interview process completed in a single day and I met with 4 or 5 people (many I had work with before). Most of the questions were asking about what I had been doing in the last few years. There were some technical type questions (e.g. draw a block diagram of my most recent FPGA, write VHDL code for a flop), but nothing too bad.
