After the initial discussion, I had an interview over the phone. The engineer over the phone asked questions about my resume and a few design questions. I was informed after 2 days that they want me to come for an in-person interview.

I was surprised to see how many people were there for the interview at the same time I was invited. It was a mini job fair :). I had an interview with directors, engineers, and HR. I must confess I was not grilled either by HR or engineers. They asked things about my resume, what is the toughest project you have worked on, how I feel about their culture, etc. I was only posed only one technical problem.

I was informed later that it didn't work out for me. The group I was interviewing with handled all the communication very nicely. My only regret is that they rejected me without testing my technical skills.
