Max Area of Island: https://leetcode.com/problems/max-area-of-island/
Minimum Remove to Make Valid Parentheses: https://leetcode.com/problems/minimum-remove-to-make-valid-parentheses/

Completed both the questions, did dry run and explained run-time complexity (O(mn) for the first and O(n) for the second question), during dry run had minor bugs in the code which the interviewer pointed out and I fixed immediately. But it was a reject. No specific reason given. Maybe lot of good candidates already in line?

Any feedback/similar experiences?
