One round with a recruiter, two technical rounds, and finally a long onsite interview.

The onsite consisted of a one-hour presentation and questions on past work, followed by four interviews:

• One LeetCode technical interview.
• One system design interview.
• One personal/light technical interview with the team lead.
• One questions/free-flowing conversation with the principal engineer.

Time felt very short, impossible to speak at length on any single topic.

Depth-first and breadth-first search, code review, and heap/stack were technical topics. They also asked about general rocketry knowledge, wanting to identify the ability to intake new information.
