LinkedIn Senior Software Engineer interview questions

The process was smooth and it was a very positive experience. The phone screen had 2 coding questions (Leetcode easy). This was followed by the onsite, which had 5 rounds. Round #1: Behavioral - with a hiring manager (not necessarily the one you may get an offer from) Round #2: System design Round #3: Technical deep dive - You get to talk about some project of yours in detail, without violating your NDA of course Lunch: Also behavioral round. Round #4: Coding Round #5: Coding The interviewers were nice and not intimidating. You can genuinely feel the positive vibe in the company. What I liked was the detailed feedback I received at the end which clearly mentioned that even though I had done well, more was expected from me as a senior engineer especially in the system design round. I was able to apply that feedback for subsequent interviews.

One phone screen with two people where they asked 3 questions. This was a very positive experience and I hoped that(short and intelligent algorithms) should be the way to test your coding skills rather than a twisted integer permutation algorithm. I was invited onsite and had to talk to 6 interviewers with two algorithms rounds. I did well in technical communication, system design, culture fit & team interaction rounds. Algo rounds are pretty confusing. One of the interviewers asked about how to find a squareroot of a given number and I came up with a couple of O(log n) solutions and picked the correct one and coded for it. He corrected few buggy lines and I think I made a positive impression. I am satisfied with this interviewer. But my second interview was pretty weird. Question was incomplete. We kept on changing the inputs whenever he felt like he missed to cover a case. I was so confused and by his last fill in the blanks of his own question finally I was clear on what he wants as the output. The solution is a loop of twisted integer permutations. As I was giving him my thoughts on the solution he kind of drove me to the solution which is to create N number of trees with integer permutations. It's a load balancer algorithm. I did my best to write down pseudo code for this algorithm as I didn't have enough time to code for this. I kind of wrote the string permutations algorithm and tried to modify it to the needs of this solution. Not sure how he accessed my skills by it. He barely has a couple of years of experience so I might not have made the cut if he made an academic level assessment of my solution. Still waiting to hear from the team but I am worried now about that final algo round otherwise an excellent interview process.
