Had a total of 3 interviews before I was offered a role; Two interviews with engineers and leadership, and one with HR. The interviews were fairly simple, with mostly behavioral questions and questions about past experience, and how I handled different situations with respect to decision making, work flow and team communication. There were some essential technical-leaning questions, though nothing too complicated if you have a good grasp of early engineering and physics courses. Everyone I spoke to was incredibly friendly and helpful, and HR was very supportive and quick to respond in the onboarding process. Overall, a smooth experience which bodes well for an inviting and communicative culture.
