Round 1

Questions:

  1. Solve Zig-Zag Traversal of a Tree (LC Medium).
  2. Variation of Longest Increasing Path in a Matrix (LC Hard) with English alphabet letters instead of numbers.
Candidate's Approach
  • For the Zig-Zag Traversal, I explained my approach but faced confusion when the interviewer insisted on using two queues.
  • The second question was introduced with only 20 minutes left, which made it challenging to devise an efficient approach for the LC Hard problem.
Interviewer's Feedback

No feedback provided.


Round 2

Questions:

  1. Group Anagrams (LC Medium).
  2. A fairly straightforward 2D Matrix problem (LC Medium).
