Candidate interview experiences
First-hand accounts from people who interviewed at Duolingo.
Product Management Intern
For the internship, they made me design a completely new feature and create a deck to explain it in detail for the engineers. This was before they even looked at my resume. It seemed like they wanted free work. But I really wanted to work there, so I did it. After spending several days working non-stop and creating a strong feature, I got a generic rejection email. It felt like a scam for unpaid labor.

Product Manager
This was a very structured interview process. There were two rounds in total, with 2 interviews in the first round and 3 interviews in the second round. They clearly communicated that each interview would focus on different skills like Data/Analytics, Product Design, UI/UX, Strategy, and Cultural Fit by sending a document detailing what to expect. The timeline was also very clear. However, the process could have been faster.

Product Management Director
This company is using candidates to source gamification ideas for their Product Management roles, specifically the gamification Lead or Director of Product Management position, which has been open for over six months. They interview many PMs, gather ideas by picking their brains on gamification, but they do not extend offers. I know this because five other excellent, highly qualified PMs I know had the exact same experience. I went through the whole process myself, including a take-home prompt and multiple interviews, only to be rejected with a generic email full of errors and no feedback. It was a terrible experience. The hiring manager, who has a consulting background, conducts an estimation round where candidates must perform calculations without a calculator or Excel, emphasizing precise answers. He believes PMs should do 'back of the envelope math,' which is an outdated and irrelevant expectation for product management. This preference seems to stem from his own biases, as it limits the candidate pool to those with consulting or math backgrounds. Some interviewers deviate from the recruiter's described format, surprising candidates with unexpected interview types. Additionally, interviewers with limited gaming knowledge sometimes dominate the discussion with basic questions, even when the panel is ready to move on, which is problematic for a specialized role. The rejection email I received was a copy-paste mess, including the phrase 'we are moving forward with another candidate,' despite the role remaining open for six months. This tactic of keeping a role open without intent to hire, purely to gather ideas for free, is highly unethical, especially from a company like Duolingo. Their claim of a 'high bar' is not credible, as top companies like FAANG or gaming industry leaders fill roles much faster. This indicates a broken process, unrealistic standards, or a lack of genuine intent to hire. They've rejected highly skilled PMs, making me question their entire hiring process. This rejection was particularly disheartening as I admired the product and the domain, and I spent weeks wondering what I did wrong. Discovering the pattern with other PMs revealed the issue lies with Duolingo. Ultimately, I wouldn't want to work for a company that disrespects candidates' time and treats them so callously. I'm now completely put off by the Duolingo brand, and I advise anyone considering this position to avoid it.
