I applied online. I interviewed at Duolingo in Aug 2020
Interview
Got the online assessment through Hackerrank, in which I had to solve 2 questions in 90 minutes. Was given a graph and string problem, Leetcode medium-hards. I did not get those questions and was rejected afterwards.
It's a standard recruiter screen followed by a phone screen and then another phone screen before finally reaching an onsite. It's a long tedious process. Would not recommend for people looking for a smooth process.
Was given an OA on code signal that had 4 questions. A lot of it was about graph traversal algorithm. I did not pass all of the hidden test cases for one of the questions, probably why I did not get moved to the next round.
