LinkedIn interview questions

I got an email from LinkedIn 1 week after applying for the job to schedule a phone interview with the recruiter. I had the first interview with the recruiter a couple of days later, then after 3 days I had a phone interview with the manager and then after a week I went to an interview at LinkedIn where I had to present an account report (brief gave to me a week in advance to work on it and bring a Power Point presentation) and afterwards a deep interview with 2 managers - one in the same room as me and another on online.
