You can only avoid so many meetings though. In software most teams have some kind of regular standup schedule. How do you know that the standup times of 2-3 jobs won't overlap before starting those jobs? Or what if the standup schedule for one jobs changes and now you can't attend? You can only miss so many of these before it's a big red flag.
Not saying it’s scrupulous but it’s discussed as well - they generally have two laptops and apparently have two zooms going at the same time at times too it seems. I can see how you could choreograph around two stand ups like that with practice!
