This was for new grad.
The first part is a coding challenge via hacker rank. This contained 2 medium level questions in 45 minutes.
If you pass that, you schedule a virtual interview for one hour. My interviewer asked me a medium level question and had follow up questions for it. You can only do this interview in Java, Javascript, and Python.
If you pass that, you get scheduled to onsite. There you get 2 technical interviews, and one pair programming interview in Python (You are not required to be proficient in it). I got asked one medium-hardish level question in each of the technical interviews. All interviews were one hour long at the onsite.
Even though I thought I did well in the on-site interviews, I was not extended an offer. Due to company policy, they were unable to provide feedback. However, I felt they treated me well, so overall it was a positive experience.
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)
