LinkedIn Sr. Software Engineer interview questions

[Coding round 1] 2 questions. 1 Easy and 1 DP DP question was unnecessarily hard, required 2D DP with bit masking. Interviewer was fairly new, had ~3y experience and was dead set on the optimal solution for the hard DP problem. If you're interviewing with Linkedin make sure to blindly memorize leetcode solutions in case you get a junior interviewer.

I got a call from recruiter for technical phone screen round. She mentioned I would be expected to solve two DSA questions. I was asked 1 dsa question , Find leaves of binary tree leetcode question. I was able to give optimal approach in 15 min. Interviewer didn’t understand it and went on to ask about 1NF, diff between unqiue key and primary key and indexing. He also asked another coding question in last 10 min. I was able to give answer to the first part.
