Met about 8 people, most of the questions were fairly straight forward. Be prepared to go through and explain what you have listed in your resume. There were some questions on Nyquist sampling and what you see at the output when the Nyquist sampling is violated.

very good, challenging. the interviewers seemed very skilled and professional, and the questions were not so common. when asked a question I recognized they tweaked it nicely and had me think more on what I already knew. I had 2 interviews in 3 days, which is nice and efficient, handled directly with the engineers and managers. met with 4 different persons. the chemistry between them seemed very good.
