1. First round – He introduced himself and asked me to introduce myself. Then he asked about one of my project listed in my resume which was related to DBMS. Then he asked me a question about indexing, hashing and drew a table and asked me to index it. Then he asked a puzzle ( a solid cube which was black from outside is divided into 125 equal cubes, then find the total number of cubes with exactly 2 faces black). I tried it for sometime and did it step by step. He provided me hints in between. The only main thing in that interview was grabbing the hints properly.

Second round- It was a subjective coding round. He asked me to write the code for least common ancestor of the tree. Then he gave me some test cases and asked me to dry run them. Then He asked me to optimise it for bst and gave some more test cases. Then he asked me to optimise it further and that’s it.

Third round- It was the final tech round and it was with the seniormost person from the team. He was the director for some technical division at Walmart Labs. He asked me about all the projects listed in my resume for atleast half an hour. Then he asked about my programming language preference which was java.
