My phone interview was on 25th jan 2022, Interviewer was calm and we spoke about resume and background for 20mins and the he asked me to solve below questions:

https://leetcode.com/problems/valid-palindrome-ii/
https://leetcode.com/problems/binary-tree-maximum-path-sum/

I was able to solve the first question quickly, then he asked to me to dry run few test cases and then asked me to write some testcases.

I had not solved much questions on trees, so i struggled with question2, I took all possible hints and finally i was able to solve it.

But got reject after few days:(

Hope this experience helps, Thank you
