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.
