People can get help of course but that's going to be the case absent effectively a remote proctored assignment. And now you're back to effectively in-person.
I would vastly prefer an "in-person" interview in which I wasn't expected to speak to the interviewer to the in-person interviews we actually have. There is a world of difference.
At that point "take-home" may not be the best name anymore, but "remote interview" just sounds like it's an interview over video. Maybe "async interview"?
But it wasn't a leetcode-style one (which are common), it was a skeleton of a React app, and I had to implement certain methods to tie it all up together.
The timer would start ticking from the moment I click "begin", and it will warn you that the timer will start after you attempt clicking (so that you don't trigger the timer by accident).
