Spectrum interview questions

Got a call from a recruiter to see if I was still interested in the position and to confirm my salary range. After that scheduled an on site interview with the hiring manager. Asked me about my experience, wanted to make sure i was a good fit for the company. Asked a few technical questions which i honestly let him know i did not know the answer. Looked at the clock and next thing I knew we had been talking for over an hour (always a good sign, means they’re interested) there were a few trick questions. I left the interview thinking yeah i definitely bombed that, just over analyzing everything i thought i stumbled on. But thankfully I got a call back from the recruiter 3 days later with a job offer.
