I have had the exact same experience with the exact same kind of person. We used to be in the same team for years and after we collaborated once, I absolutely hated any work interaction related to his him or his work. Outside of work we got along well, he was fine, socially stunted, but that's OK.
When the layoff time came, everyone had to scramble to move by themselves to a small selection of teams. The second I heard that guy was interviewing for the same team as me, I had gotten an offer at that point, I told the hiring manager, me or him. That's how bad working with those kinds of people can be. He ended up elsewhere and I'm still in that team. I just could not deal with him anymore. Perfect interviewer, but couldn't write production code to save his life... He's still employed by the way, bumbling around from team to team because the consequences of his incompetence take months or years to feel...
