Phone screen, take-home task, then interview with hiring manager.
The hiring process felt one-sided. Both interviewers left less than 5 min for candidate questions. The take-home task was 3 separate tasks with multiple parts, and it was due before even meeting the hiring manager.
FYI, they're very rigid about the Pittsburgh onsite requirement.
Interview questions [1]
Question 1
How would you design a lesson to teach the English articles (a/an/the)?
I applied online. The process took 1 week. I interviewed at Duolingo (Pittsburgh, PA) in July 2024
Interview
Short interview with another curriculum designer followed by technical task. Task tested ways of breaking down language lessons in digestible chunks. Unfortunately, I did not move beyond this point in the interview process.
I applied through an employee referral. The process took 7 weeks. I interviewed at Duolingo in May 2022
Interview
The interview process was comprised of several steps. After accepting my application, I was asked to complete a short task that served as the basis for my first interview. After that, I had several short interviews with people in different positions in the company.
