LinkedIn interview questions

I was first communicated by the recruiter who called me and had a normal background chat for about 30 minutes. He also gave me details about the company, culture, teams, etc. I was scheduled for a phone interview of an hour which also had coding involved. This round had one problem-solving question, which was related to Binary Search Algorithm application, went okay. I could reach a solution, and even though I took some time to reach the correct approach, the interviewer appreciated my thought process. I got mail for another phone interview which again was for an hour and I had to code online. This time it was a tough question about writing a program where given a sorted array, repetitions allowed, and given an integer, I had to return the start index and end index of that integer in the array. I chose the Binary Search approach but some modifications had to be made to make it optimistic in run-time. I failed to reach the exact solution, and hence could not clear this round. I think LinkedIn is a nice company to work with and I would surely consider applying again to it at some point of time in future.

The hiring process consisted of a brief phone interview (not technical) with the hiring manager. I was asked to come over for an onsite interview that would last for 3 hours. A day before the interview, the recruiter informed me that the interview has been cut short to 45 minutes. Couple of engineers met me at the lobby, seems like they were unprepared because they were looking for empty conference rooms right at the time of the interview. The technical questions were generally easy, if you know basic data structures/algorithms, Big O notation, you should be good to go. (definitely not as hard as google interviews). The interviewers were very nice and professional. I got the following feedback after the interview - " Interview went well. I sync up with interviewers and based on feedback the candidate has very limited technical skills geared towards C++ and little bit of scripting. Its a reject from our end" It's funny because the reason I applied for this req is because it stated "Extensive programming experience in Objective C or C/C++". Feedback to the hiring manager: you should get your requirements straightened out before you put out a req.
