Protocol Labs Software Engineer Interview Questions
& Process

First, a hiring manager call. Then, 4 more rounds. They've got a fast-track system where they'll cut you loose and cancel the rest of your interviews if you don't measure up in any single round. The interviews cover large-scale design, small-scale design, behavioral, and coding.

I was contacted on LinkedIn, and we chatted about our mutual interests before scheduling a virtual meeting. During the interview, they explained how Protocol Labs operates, mentioning their global distribution and that the role is remote. The position focuses on building infrastructure and protocols for Web3.0. They were keen to learn about my previous experience and my technical background, and they prefer candidates with knowledge in cryptography and Rust.

The job application response was really fast, but things went downhill from there. They rescheduled the first call last minute. Then, three other interviews had their dates and interviewers changed multiple times by two different recruiters. After waiting over a week post-interviews, I had to chase them for an update. Turns out, it was a no-go, with no specific feedback. Some interviewers were great - competent and humble. The hiring manager, however, seemed out of touch and insincere.
