The onsite interview process is pretty dismal when compared to other SV companies of LinkedIn's stature. My first interviewer had a strong accent, but I could indeed understand him. Another interviewer had no mastery of the English language whatsoever and could not adequately communicate what he was asking. My algorithms interview was "interesting" to say the least - the (junior) interviewer refused to accept any answer different from what he already had in mind regardless of big-O time/space complexity of my solution. This threw me off and I bombed it. I felt like I did OK-to-good in all interviews except for the algorithms interview.
