In my previous job we hired someone in a "Senior Architect" position. They had extensive experience at a larger company, but there were red flags from the beginning (including the interview, where they got visibly upset and melodramatic when they were unable to finish the algorithmic problem we gave)

Working on anything related to design and architecture with them was a disaster. They preferred waterfall over agile, didn't take feedback very well, was obsequious towards leadership but toxic towards the team they led, and would terminate collaboration with someone if there was disagreement.

The soft skills for an architect are essential, and I think that includes excellent communication skills, documentation, and ability to take feedback and constructive criticism. Needless to say, the coworker I describe fit none of those criteria. It's been pure bliss not having to work with someone like that, and helped me better understand what to avoid in the path to becoming a legitimate software architect.
