After submitting my CV, I was sent an online assessment on Hackerrank - haven't heard back yet. It was more difficult than I thought, but doable. If approved, there will be HR interview.

Behavioral Interview STAR Method: Situation, Task, Action, Result framework for answering questions. Leadership Qualities: Conflict resolution, Team collaboration, Problem-solving approach.

It was a fun process, everyone was kind and helpful. We first started with a challenging hacker rank challenge which was fun and after a while moved on to one to one meeting where
