I've hired around 10 and interviewed around 50/60.

Half the people I hired, I did so without any technical interview, I met them in coding communities and saw everyday their OSS contributions and skills.

In any case I'm not debating your method is wrong, I'm just saying there's individuals like me that don't do well in these kind of situations/exams and can easily be false negatives.

I'm also saying that this isn't rocket science, and in general trying to understand if the person is honest and hard working is much more important than his coding skills.

I've seen way too many stellar graduates leetcode ninjas being just terrible at their job or completely uninterested.

And in Europe it's hard to fire them.
