Groupon Interview Experience -SDE 2 (6 years experience)
There are a total of 4 rounds
- Least common ancestor
- Contiguous subarray with maximum sum (Kadane’s algo)
- 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.
