Many rounds of interview, smooth process. Communicative HR outlining the whole process. Overall a very positive experience but the interviews are long including a panel interview that lasted 5 hours.

Anonymous Interview Candidate in New York, NY
I applied through college or university. The process took 2 weeks. I interviewed at Duolingo (New York, NY) in Jan 2023
Everyone was very kind in the process, though the position was pulled right before I did the final interview. Started with an email to schedule, first a half hour interview, very chill, spoke with animation lead. Soon after I got the email that I made it to the last round. I was then sent an itinerary for a 3 hour schedule, I would have spoken to 5 people in total over different specifications of the job (presentation, creative, technical, etc). Before the day came I got the email that they weren't going to hire for that position after all since they wanted to focus on other departments. It was a bit of a blow but I met some very cool people in the process.

The interview process went well, a few hours after the zoom call they asked me to come in an tour the facility which I though was a good sign. Everyone was friendly and seemed to like me, I was overly qualified for the job but unfortunately, a few days later I was told I didn't receive the job so it kind of felt like they were stringing me along.

The recruiter reached out to me after applied. She gave me a couple of questions to work on. She was warm and agreed to give me extra time when I needed, but the process was still a bit vague.
- They gave me a design test to see my "thought process."

The interview process varies a bit depending on which role/level you're applying for. Software engineering roles will have several phone screen/technical interviews before a virtual "on site" day. The on site will have a few different interview types.
