I sent my resume over the internet. I received feedback for a 15-minute phone screen in about one week.

They did not call me on that day, but later asked for a 45-minute technical interview. They sent out an onsite interview notice within 3 days.

Onsite was a full day. I met eight people, 45 minutes each round. An offer was extended within 4 days after the onsite.

I can't expose the details as it is confidential. However, the most difficult question involves some low-level design questions. This requires complete familiarity with related subjects and the ability to combine them together.
