Put aside the people with small (and not so small) children at home, and observe whether the pandemic has boosted or destroyed their productivity. That is one measure for how they handle stress, and whether you might wish to trust them with a start-up or some other major project requiring quick adaptation and performance under duress. It may or may not be a measure for their ordinary performance on the job.
Consider the now-cancelled Candidates’ chess tournament in Russia. Ling Diren was one of the two clear favorites (with Caruana), and he lost three games in the first half of the tournament. That is evidence he does not play well under an extreme degree of stress. Yet he still is rated #3 in the world, from a career playing under conditions of “not a pandemic level of stress but still world-class levels of competitive stress.”
Grischuk had been saying the tournament should be called off, even in midstream. Probably he was right, but if play had continued would you have predicted him to come in first? Caruana, the American, was worried he may not be able to get home after the tournament. His play was OK but subpar, at least for a world-ranked number two. The non-favored but sturdy Nepomniachtchi was up three games, before unwisely playing a Winawer defense with the black pieces, but still he was the clear leader. How should we now revise our opinions of him?
