LinkedIn interview questions

Had first phone call with HR. Went fine. Then There were 2 phone interviews. Both of them asked traditional questions. The second technical round interviewer was very rude. Did not introduce himself. He got into the coding test directly. He asked 2 questions which I answered in 30 minutes out of the one hour interview. He had no better thing to do so he asked me trace the whole recursive code on phone. I don't know how these people judge someone's skills.. Their questions are either from leetcode or some fixed set of pool. I got a reject the next day even after answering their questions well in time.

The hiring and interview process was very long and tedious. As a recent college graduate, I expected to jump through some hoops during the interview process, but not like this. It always seemed like I was constantly being handed off. It started with an internal referral. A month after the referral, I received an email from a recruiter in their New York office to schedule a phone screen. I thought this was strange since I was applying for the Mountain View, CA office, but we scheduled a time and date. When the time arrived, I got an email a half hour after our schedule phone screen, to reschedule. This should of been a red flag, but I moved on with the process. Two weeks after the phone screen, I was informed that I was selected for a on-site interview and I would hear from a recruiter in Mountain View about a time and date to come in. It took over 6 weeks to hear from the recruiter in Mountain View. And they wanted me to come in the next week for an on-site after 6 weeks of no contact. The actual on-site interview was well organized and professionally run, great experience. But the worst part of it all was the suspense after the on-site interview. The recruiter told the group that we would hear back, regarding an offer, in around two days or by latest the end of the week (by the New York recruiter). With their current track record, I should have expected this. Never heard anything by the end of the week. I emailed and called the recruiter in New York but did not hear back till the following week. Overall LinkedIn's interview process was not well organized and there was a lot of lag between recruiters.
