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.
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.
