I applied online. The process took 1 week. I interviewed at LinkedIn in Aug 2015
Interview
I applied online and got contacted by recruiter the next day. He was very nice and quickly arranged a phone screening. The interviewer called me and asked me two questions - two sum problem, and parenthesis matching. I missed to handle one edge case and the next day got a rejection call.
The problem which I see here is that in one of the questions, I was talking about Java String internals, how a String is backed by a character array, and she had no idea of what I was talking about. That might have offended her. I have solved two sum problem and parenthesis matching problem many times before and I do not expect to get a rejection, but I got it. I am a PhD and have 4 years of experience.
Interviewed for an SDE role. The process was well-organized and the recruiters were responsive throughout. That said, the technical rounds were significantly more challenging than expected — definitely come prepared to go deep. Overall a valuable experience regardless of the outcome.
That was a real stroke of luck — when I got to the coding round and encountered a question on finding the maximum subarray sum, I had literally seen this exact problem on prachub.com a few days earlier. The interview kicked off with a recruiter screen, followed by a technical phone interview. It was intense, especially with the focus on algorithms and data structures. I also faced some behavioral questions that challenged my experience. After a final onsite round, I received an offer and happily accepted. Overall, it was tough but rewarding.
Interview questions [1]
Question 1
Given an integer array nums, find the contiguous subarray (containing at least one number) which has the largest sum and return its sum. Walk through Kadane's algorithm and explain the O(n) approach.
Overall, a good interview process and the team were very friendly during the interview process and it was very good and pleasant. Nothing in regard to negative feedback or anything as such like that.
