I'm getting pretty old and have done a ton of interviews at this point in life.
There's never been a single one that went poorly and I didn't know exactly why without a word of feedback from the company I was interviewing with.
Poorly is different then hitting 90% (maybe?) of the way there but still rejected. Or conflicting responses from different interviews. Like you did great on the coding then the next company thinks you did poorly.
