The one's i've gotten have all seemed more like tests of my puzzle solving skills than coding.

The worst ones i've had though had extra problems though:

one i was only told about when i joined the interview and that they would be watching live.

One where they wanted me streaming my face the whole time (maybe some people people are fine with that)

And one that would count it against me if i tabbed to another page. So no documentation because they assume i'm just googling it.

Still it's mostly on me to prepare and expect this stuff now.
