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...
