I applied online. I interviewed at Perplexity AI in Aug 2025
Interview
Talked to the recruiter, they set up expectation about extremely long hours at the onset. Second was a coding round. This interviewer gave me a coding assignment to do which wasn't that difficult. But the wouldn't let me think through the problem at all, they would keep interrupting you like an auto-complete. I did complete the assignment and they seemed happy with it. Was rejected, obviously no feedback but I was more annoyed by the interviewer, if you have to do thinking on my behalf, why do the interview at all? It was not like I was stuck on the problem for 5 mins, every 10-seconds, they would give me a new idea. TBH, thankful to not get through.
Interview questions [1]
Question 1
They asked me to build a small project to simulate a particular system.
Just met a hiring manager, didn't get a chance to do on-site interviews after that. Seems like they were looking for very specific knowledge / experience. I don't have more info about the follow up process.

Leetcode style question which adds on after you finish eventual parts. Question was implement a to-do list. Required state changes and dependency cycles. They also have predefined tests for each of the parts.
