I applied through a recruiter. The process took 1 day. I interviewed at Groupon (Mountain View, CA) in June 2011
Interview
Of the five engineers who interviewed me, only one asked questions that would distinguish a good engineer from a mediocre one. One interviewer asked a series of puzzles -- most of them easy and which told the interviewer nothing about my ability to write readable, testable, or correct code. One interviewer ran out of questions after eight minutes (I checked my watch). One was a front-end engineer who asked me questions about front-end work even though I very clearly stated that I was a backend engineer and had no interest in working on the front end.
The technical staff seemed fairly junior and the company appeared to have tremendous technical debt.
Interview questions [1]
Question 1
Probably the best question I was asked went along the lines of: when designing an API between front-end/UI code and backend servers, what technologies would you choose and, more importantly, why would you choose one over the other?
I applied online. The process took 1 day. I interviewed at Groupon (Prague) in Oct 2024
Interview
Interviewer late. Wouldn't proceed with interview without a camera on; cited cheating on an online test being an issue. It's a great way to kill any kind of trust dynamic within the first couple minutes - massive red flag for me and very indicative of company culture.

I applied through a recruiter. The process took 2 weeks. I interviewed at Groupon in Apr 2023
Interview
I was contacted by agency to join groupon as a contractor. I did first round of interview with a coding task leetcode easy and some SQL query. I was asked for a second round and after scheduled the date they just cancelled with the explanation they already found the java developer. Very unprofessional and not respectful of people time.
