I have completed 5 phone interviews with them.

They ask LeetCode medium problems pretty much every time. They usually start with simplified versions of the question and build up once you solve it initially.

Occasionally, the interviewer may be unwilling to help, passive-aggressive, or difficult to understand, but usually they are quite helpful.

Make sure to practice solving hard problems with someone watching. People often blank when asked questions that require significant thought for the first few times.

They don't really ask behavioral questions, but they will ask you to describe your experience and interests.
