Multiple rounds of LeetCode-type questions. Their level was between medium and hard, and in many cases allowed for many different solutions and improvements. The whole interview was code-agnostic, and nobody cared for typos.

Professional and enjoyable, though not as intense as I expected. It was definitely too lengthy and time-consuming. It would be much better if the interview process didn't always have to be 4 or 5 rounds, but I do understand why.

Upfront, consistent, and challenging. I received an email from the hiring screener for a call, followed by a take-home assessment and a panel interview. I didn't get the role, but they were professional and respectful.
