There were four separate interviews- technical phone screen, first technical round, behavioral interview, and final technical round. Each technical round involved two coding questions in 45 minutes, and the behavioral interview asked standard questions.

The interview process, from my initial communication with the recruiter, was exceptionally smooth. They provided me with valuable resources to prepare for the interview, btw the interview was back in 2018, so my memory is a bit fuzzy. However, I can confidently say that the overall experience was both highly professional and welcoming.
