Personally - I'd not hire that person. Sounds like they're completely inflexible and unable to adapt to constantly changing environments. Maybe really good for maintenance work or something but if you do startups, work on growing products, do major feature work that has a lot of back and forth, etc. Very likely to not do well at any of the jobs I've had.

Yeah I've never done any kind of software engineering work that wasn't highly collaborative.

Even maintenance work is highly collaborative in my experience. Maybe even moreso than developing new features in some ways. As a maintainer you often need to work to understand the intentions of the people who originally wrote the code.
