I applied through college or university. The process took 1 week. I interviewed at Groupon (Chicago, IL) in Feb 2016
Interview
I applied through my college's career fair and got a call for on campus interview really soon. My first round was with a software engineer where we worked through the code of a tic tac toe game. It lasted for half an hour and went pretty well. The next round was immediately after with a data scientist who was very biased. The questions weren't informative enough and he wasn't interested in anything that I had to say.
Interview questions [1]
Question 1
How will you design a expert system with data about users of Groupon.
I applied online. I interviewed at Groupon in Jan 2026
Interview
Smooth, structured, fast responses, good overviews of the role and expectations from interviewers. Exposure to prominent figures in the company. Refreshing that interviews weren’t too structured, and conversations flowed naturally. Something that is rare for such established companies.
Fun to learn more about the company. Not sure if it was a good fit, but met lots of cool people along the way! Decided to pursue other things. Great that it was started in Chicago.
I applied through college or university. The process took 6 days. I interviewed at Groupon (Dublin, Dublin) in Nov 2016
Interview
Applied through on campus meeting. One hour interview on site in Dublin. Very nice people, didn't get the offer unfortunately. Brush up on your fundamentals and data structures/algorithms because they will ask you about them
