I applied online. The process took 1 week. I interviewed at Groupon (New York, NY) in Dec 2018
Interview
Applied on Linkedin. Contacted by recruiter within the same week. Everything went fine and recruiter asked availability for next round of interviews. Never heard back thereafter. Didn't expect to be ghosted after asking for availability. A simple rejection would have sufficed instead of keeping the candidate in the dark or getting hopes high by asking availability for next round.
