LinkedIn Software Developer interview questions

got contacted by recruiter on LinkedIn. did 2 phone interviews and most questions can be found in interview books or on glassdoor. Made it to on-site and had 5 back to back interviews. it was quite tiring. I failed the design interview and some coding. there was no dynamic programming questions. lunch interview was easiest as we just chatted and one coding interview was easy but got grilled a lot in the other one and that's where I also failed some as they wanted to ask me two questions and I only got to one.

Had 2 phone interviews, supposed-to-be-five-but-turned-out-to-be-seven rounds of onsite interviews. 3 were system architecture and design related rounds. Found those a bit hard as compared to the coding & algorithmic questions. Overall experience was average. Post lunch interviewers were less experienced I'm assuming, because one of them yawned non-stop and a couple others had taken a vow not to speak during the interviews.
