You’re complaining about the process being ageist, but I think you need to wake up to reality that life is not fair and sometimes you have to make sacrifices. In our case, if you sacrifice your life for 1-2 months it can set you up at a nice job for the next 2+ years. That’s so much better than what most people have it like.
Every minute I spend on take-homes (oh dear lord the take-homes) is a minute I'm dumping the childcare responsibilities on my wife. And she heads out to work, so I do a bunch of childcare in the mornings/evenings.
Then I also have a full-time job. Like, unless I want to stop sleeping I don't have a whole lot of time to do this stuff.
I just (mostly) finished one and it was because my wife took the baby out to meet other mums.
The worst part is that I have lots and lots of work online, plenty of GH repos and a bunch of really selective companies on my CV. And yet still every time I need to prove that I can in fact call read.csv and do a bunch of data manipulation/analysis.
And I love doing this work. I can only imagine what this is like for someone for whom it's just a career (which is totally fine, tbh).
But the thing is, lots of the experienced people you want to hire will be in this position, so it's worth accounting for.
I'm slowly coming around to the view that the widely accepted process is ageist. Whether that's deliberate or an externality I'm still undecided.
