To be clear, i am talking about: you apply, they send you a response (sometimes automated) telling you to do a couple hours of work, and only then will they decide if they want to speak with you.
This a great way to waste one's limited time on a role that might not even be a fit. If they aren't even willing to spend 15 minutes talking to you first, i would encourage everyone, at any level, to bounce. If they are at all serious, they'll speak with you first.
And I'll also highlight: you never know when they are using you for their own goals, like AI training. Or if it's a ghost job. Or if they aren't hiring for your state. Lots of stuff can come up that would make your work null & void.
To prevent burn out, you really have to guard your time. companies can structure things to be highly optimized for them, and very expensive for you.
For instance, in my recent job search for a new grad role, I had to do an OA for every company but Jane Street and Databricks (props to them).
