I don't think I projected that vibe. I knew ahead of time that the architecture interview was going to be the hardest part for me, and made an effort to show that while I had gaps in my knowledge, I wasn't going to be afraid to ask questions and have discussions to make it possible to get work done. I have a bit of an aversion to unearned overconfidence so I like to think that I did not project that in the interview, but obviously I can't experience myself from the interviewers perspective.
When I interview junior candidates, attitude, interest, and capacity for learning are more important to me than specific knowledge.
Anyway though, it was their choice, and I clearly didn't demonstrate what they wanted to see. Not getting that job left me in the right place at the right time for a job that I really love, so... ¯ \ _ ( ツ ) _ / ¯
