I applied through a recruiter. The process took 1 day. I interviewed at LinkedIn in Sep 2012
Interview
Received a inMail from one of the recruiters for a interview scheduling for a position that I haven't applied. I sent my available date and times. I haven't received any response from the recruiter so I sent an inMail and asked what happened. I haven't received an answer to that mail either.
I would have expected a respectful process from a company like Linked in but they let me down.
The process took 4 weeks. I interviewed at LinkedIn (Mountain View, CA) in Jun 2012
Interview
LinkedIn recruiter contacted me thru LinkedIn itself. Had 2 HR phone calls, asked very standard questions. Following are 2 x 45 mins technical phone. They are relatively easy. Then on-site which consist of 5 rounds. After passing all that, had one last phone call with the team manager.
Overall, It is a very pleasant and smooth interview process. LinkedIn HRs and Interviewers are very professional and friendly. HR usually respond within 2-3 days. Work environment are very good!
I would definitely apply again if I weren't in!!

Interview
I had couple of phone interviews with different teams. My read of LinkedIn is that they require prebaked people in their technology stack. This is something big companies (like MS/Google) do only for contractors. For full time employees its always a long bet to hire great people who have the interest and potential to grow the company. My first interview was with for mobile phone dev. The person was very nice however was very disappointed that I don't know javascript (my resume does not even have JS written as a skill). He asked me to find an element in a sorted array which I did correctly to his satisfaction. But, expectedly, the recruiter said team does not want to move forward.
My second interview was for backend dev. I know java because of my android background but I am a .NET person. The interviewers expected someone who is great at Java. Any ways in one hour first there was tech screen questions on Java. Then they asked two questions which I think is flawed because the interview and interviewee are both rushed. First one was really easy (one of those on glassdoor). Second one was to write a deep iterator. This is a tough question to complete in 20 mins (I mean to think the algo and write code). Also, I felt the interviewer was rude. This was a pass/fail question for him (write code for me or hang up the phone kind of attitude).
Only plus point is that their recruiters are really nice people.
