The all process was very smooth and quick. A recruiter contacted me via Linkedin and scheduled a first phone screening interview (questions were mainly around my background and achievements).
The second interview was again on the phone but with the hiring Manager, who made me feel at ease since the beginning. He was very nice and professional and he asked mostly behavioural questions.
Then I was invited to the onsite where I interviewed with him and a member of his team. In the first half an hour they asked me again few behavioural questions, then I had to do a presentation about me and why I want to work for Linkedin. Last part of the interview was a sales play role.
I didn't get the job as they finally chose an internal candidate but the all process was very positive. HR was also very proactive in giving feedback after every round of interviews.
