The interview process began with a casual introductory call with the recruiter to discuss general background and interest.

This was followed by a phone screen with a manager, which covered both behavioral questions and some technical discussion.

The final stage was a virtual onsite consisting of three rounds:

• One focused on system design.
• Another on coding and problem-solving.
• The last round centered around behavioral and team-fit questions.
