And just after I wrote the previous post, I come across the kinds from the other side.

On one hand, there are people who not only do their job well but also think of possible loopholes and have it taken care of or answered before it crops up and on the other hand, there are these kinds who do even read an email completely before replying.

I think in an interview process, one of the most important qualities to look for is to make people read emails and ask them to respond. Simple task but the reply could really startle your knowledge of the person.
