LinkedIn interview questions

Initaially contacted via linkedin by a recruiter requesting permission to contact me in relation to a role. Followed by a telephone interview with the same recruiter. Then progressed onto a 2nd telephone interview with Hiring Manager based un US. Next step was to go into the linkedin office for an afternoon of interviews - met with the semior team manager and then 2 managers that the candidates would be working with on a day to day basis. The next portion of the interview were via video conference with staff in Californina - A 45 minute conversation with the hiring manager which included a working example of the role and how I would approach the issues faced within the role and the final part was a conversation with 2 existing business analyst from US team, his again included a presentation and working examples. Unfortunately I made it to the final round but was unsucessful in recieveing an offer.

A very structured and detailed interview, however the interviewer himself was arrogant and acted like he was doing me a favour. I get that LinkedIn are doing well, but having a superiority complex doesn't reflect well on the culture.
