[joined ~3 years back as an Intern so process might have changed] Take home assignment, followed by a 1.5 hour call about why I did what I did. Then another call to check depth of understanding of backend concepts. Followed by a culture fit round. Hired.

Simple interview process. Started with system design round. Then a backend assignment was given based on which interview was done. Post the interview there was a cult fit round where I had a discussion with someone in the management team
