I applied through a recruiter. The process took 1 week. I interviewed at Duolingo in Oct 2021
Interview
I was given a hackerrank to be done within 5 days of receipt. I didn't manage to get to the next round. The questions were leetcode medium/hard. Related to DFS and backtracking.

Question 1
The question was about finding unique words in an owl dictionary where words are the same meaning if one word can be derived from the other by removing exactly one letter; e.g caw and caww have the same meaning, so do caww and caaww. By transitivity relation, caw, caww, caaww all have the same meaning so comprise one unique word.

Interview
Had the first round interview. I thought the question was doable. Just make sure to know data structures and you should be fine. Solved it without much help but still got rejected. The interviewer was chill though.
