Pretty standard software engineer interview process: initial phone screen (by VP of engineering), technical phone screen, then in-person interview. The technical phone screen used CodeBunk to write code. The in-person interview used a white-board for programming problems. Overall it took a month and a half to get from screening to interview, and they went silent so long I wrote them off as an option. Other than the typical software engineer questions, they were really concerned with how passionate I'd be for solar power and their product.

The interview process spanned about four weeks (initial response to application -> offer date). Although, the timeline could have easily been cut in half if I hadn't requested extra study time between interviews. All parties involved were polite, engaging, and disarming. The sessions break down as follows: - Initial Interview: HR (~0.5hr) - Technical Interview: Senior (~1hr) - Technical Interviews: Mixed Levels (~4hr) - Final Interviews: Leadership (~2hr) Technical interviews, although fun, are always a bit nerve-racking. I'm sure the interviewers sensed my tension and responded with efforts to put me at ease. The actual questions weren't necessarily the most difficult, but expect follow-up questions to progressively get more difficult as they explore the depth of your understanding. I never felt like I was being presented a trick question and the interviewers did a great job providing nudges and confirmations. Overall, the sessions ended up feeling like a conversation with an industry expert re: material we are both interested in.
