Groupon Software Engineer interview experience

Posted Feb 2026 · Candidate report, summarized by Dataford

My first step for the Staff Engineer role was a coding test on Coderbyte, and it felt a bit unfriendly from the start.

The test had exactly two questions and gave me 75 minutes to complete them.

The first problem was an LRU cache implementation, and the second was a binary search question at a medium level. I focused on getting the logic right and finishing within the time window, and I ended up passing the test.

What stuck with me most was how narrowly the round was scoped: just two problems, all in that one Coderbyte session. I didn’t get a different kind of feedback from this round beyond whether I passed, but overall it was a straightforward checkpoint that I cleared.
