Applied online on their website. A recruiter reached out by email and set up a coding interview. Got a follow-up email saying they weren't going to move any further in the interview process.

A quick chat with the recruiter led me to initial contact with a third-party coding challenge. It was moderately difficult but not in my wheelhouse. The person leading the interview was nice and seemed well-suited for the task.

It was a standard tech interview, basically LeetCode problems. It included data structures and algorithms, all conducted via a custom applet. It was educational material, and I learned things.
