I applied online. The process took 1 week. I interviewed at Duolingo in Mar 2014
Interview
I applied online via the website from overseas, and the next day I was given a take-home programming task with one week to solve. After that, I had a non-technical phone interview, and was given an offer on the spot (contingent on background checking). The take-home task was not particularly difficult, although having an NLP background definitely helps -- not that you actually need to know NLP in order to solve it.
The whole process was straightforward, not stressful and surprisingly fast. It was not nearly as traumatic as many other processes, and the task was fun to solve and down to Earth (not some random textbook exercise, but an actual problem faced by Duolingo).
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.
