This was for a new grad position. The interview process was HackerRank -> phone interview -> final round.
They got back to me after the phone interview a month later. It has now been almost a month since the final interview.
After sending a follow-up email, the recruiter did not respond.
I would not recommend applying to Duolingo. It is extremely unprofessional to spend five hours on a final round interview and not receive any answer.
