Groupon Interview Experience -SDE 2 (6 years experience)

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.
