I applied through a recruiter. The process took 3 days. I interviewed at Duolingo
Interview
The Interview comprised of a Phone Screen and On site interview. They were super friendly and inviting, not intimidating at all. You will get the response very very quickly. I didn't get an offer, but it was a very good experience and interview. Would recommend, it's pretty low stress and casual and the people that work here are awesome.
Interview questions [1]
Question 1
Design an algorithm to do a task, and code it. Write tests as well.
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.
I applied online. I interviewed at Duolingo (Pittsburgh, PA)
