Received a referral for an HR interview with a recruiter for a SWE position. The recruiter was fantastic and I can tell the company has put a lot of work into their candidate experience. The company scheduled me for a technical phone interview with the VP of Eng for the next day. This is where things got interesting. I was told explicitly in the scheduling email I could interview in any language of my choosing; however, pretty much the first thing I was told in the interview was that I could not interview in JavaScript, the language I've been developing in for the past year. Although I have decent experience developing in C++ and Python, I'm pretty rusty on these languages and wish I would have known beforehand so I could review the language semantics. Being told I could not work in JS really threw me off my game. I was asked to implement JavaScript's setTimeout() function in any language other than JavaScript. I struggled through it and came up with a mostly-working solution in Python with JS pseudo-code. Not my finest interview. Told in a friendly email they would not be continuing. Overall, I think the company is excellent and worth interviewing at. A shame I whiffed it on the second phone screen!

Screening call with the recruiter, then moved to a 75-minute technical interview with another software engineer and a manager. That involved System design and coding problems. After that, you moved to a final behavioural interview.
