I would argue that the kind of stress involved is different. I.e., social stress, as I experience in whiteboard interviews, has nothing to do with the stress of an impending deadline.
For example, when you're in charge of a production service, and that service goes down, there is a lot of social stress to "just fix it", oftentimes under non-ideal conditions (just like solving a problem on the spot in an interview).
It's much more likely you're typing some bash commands or restoring a postgres database.
I've had to solve DS&A problems a few times in my career, and I've had to solve production outages, but never both at the same time.
I don't think that's a conclusion you can actually make, it's still a very different kind of stress, especially for someone introverted. When I'm being evaluated, the stress is crippling me - I'm overly nervous and can mess up even the simplest things; even finding correct words can be hard. However, when I'm in a urgent situation where something needs fixing, or deadline is passing, I become focused, assertive (but also easily irritated) and take charge much more easily than usual - and that short-term stress actually helps there. Those are very different situations that make people react differently.
