I used their interview prep course and went in with the mindset that it's a conversational, less formal interview. However, it ended up being strict and offered no help. For example, I mentioned forgetting a method command from Maps. They responded

First round of technical interview. Went over previous technical experience and focused on projects that use data. Did a LeetCode hard problem. Had a Zoom call prior to the interview describing the process and tips for how to succeed.

The interview lasted about an hour. The first 20 minutes consisted of several behavioral questions (leadership principles) plus one LeetCode question. It wasn't really hard if you were fully prepared. The interviewer was nice.
