Counterpoint: They already know you can't "do" the job-specific tasks because you don't work there yet. If you know the tools, that's extremely helpful as they teach you what to do with them. If there's pile A and pile B and they're mostly the same except B already knows JIRA or Visual Studio or whatever, then that's a legitimate differentiator.

When the existing team is forced to get new software, there's a presumption that they already know what tasks the tools are supposed to help them do. There's no "other pile," so might as well suck it up and kill your productivity by ten percent for a year. It's okay though; you can improve it by 1% from the original baseline for nine years after, because the McKinsey and Accenture people totally promised us that makes sense. Rinse and repeat.
