Asked me a few questions about basic c++. very nice interview. explained about the company and about the perks and then technical questions for about an hour and a half.

Initial "warmup" questions were more focused on my familiarity with different languages, and hands-on experience with them (including popular frameworks and modern capabilities). The majority of the interview was invested in open questions, where the interviewer and I freely discussed a solution. I did not make the cut. However, I would like to mention that I was VERY surprised and pleased with the time invested to explain my errors, and how I can improve. Maybe in the future...
