There are a total of 4 rounds

Round 1 Least common ancestor Contiguous subarray with maximum sum (Kadane's algo)

Round 2 Design google sheets with concurrent editing. Hint: Use chunks for storage and define sync methodology. Use any gossip protocol.

Round 3 Hiring manager round I was asked in detail about previous projects, chat protocols and other bot related questions (since I had worked on them).

Round 4 Bar raiser It was more focused on how one presents themselves. Detailed questions about previous projects, most interesting, most challenging, etc.
