Online coding assessment and then phone chat with recruiter
After that, there are a few rounds of interviews including a pair programming section where you debug a piece of the codebase
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)
