I first had a phone conversation with the recruiter, during which some basic technical questions were asked. I was then given a series of study guides and a month to prepare. A month later, I had a phone interview that lasted about an hour.

1 hour OA, 2 online code challenges. 2 rounds of phone interviews, each round has 1 hour and 2 code challenges. 5 rounds of onsite interviews, with 2 code challenges for each round. All the code is written on the whiteboard without any IDE or even
