I'm pretty sure there's studies out there that have proven unless there's some attention deficit, no one is better at multi-tasking than individually addressing each topic. Have I seen these studies? No. I am just assuming.

Just duck the straight yes/no answer and go on to say you are extraordinarily competent at "maintaining superior results" while multitasking.

Maintenance of the same results would be a lie for an IxxJ, but maintenance of "superior results" is a categorical, more vague definition of the word, and thus lets you answer it the way the phrasing clearly expects a "right" answer without any lying involved.

Any idiot that phrases a question like that clearly doesn't know what they're looking for when they're hiring someone anyway. They just want a competent and likable employee, which you are. Tell them why they should want you.
