Do online programming tests have any value (except for providing an evidence to potential employers) in terms of evaluating your knowledge, or a they too broad or too narrow in general?

I do not want to ask candidates questions, but rather give them several problems to resolve. The reason for this is that I've seen people be excellent with theory, but when confronted by a real world c# issue, just couldn't hack it. These c# problems should be simple enough that it won't take more than 1-20 minutes to resolve, yet comp...

Do an...

Distant from each other. For example, for points: (0,0), (1,1), (-8, 5) - the most distant are: (1,1) and (-8,5) because the distance between th...
Hi All, I have recently started applying for .Net jobs. I currently work in a sales role with a large telco.
