I was contacted by a corporate recruiter on LinkedIn. I had one or two interview screenings with the recruiter, and was then invited for an in-person interview. Before the interview, I had to prepare a case study based on information sent to me by the recruiter - I had about two days to prepare. The in-person interview consisted of a group meeting with several other candidates, and then a series of 2-on-1 breakout interviews with different members of the team. It was an elimination process. I made it to the final round and presented my case study to a small group of interviewers. The whole process took about 2 1/2 hours. I got the job offer about 3 days later.
