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.

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.
