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.
They asked to explain io_uring, and if I programmed Linux kernel.
The following metrics were computed from 3 interview experiences for the Perplexity Senior Software Engineer role.
Perplexity's interview process for their Senior Software Engineer roles is extremely selective, failing the vast majority of engineers.
Candidates reported having very negative feelings for Perplexity's Senior Software Engineer interview process.
