Interview took aprox 1 week. All interviews were 45 mins First interview with Manager, then 4 other Technical experts. then again manager. They directly went to technical rounds. One coding question and one math question for each interview.

There were two phone screens both fairly technical, followed by a very technical oriented in person interview. Asked to give a presentation to group at start and then met privately with several engineers with technical questions. After that I was asked to write fairly simple computer programs one in a language I did not know for them to eval my problem solving skills. A lot of stone faces in the interview group. Not so friendly.
