I somewhat know the difference between kind and type, but I want to know it in detail so I can be able to use these words in my daily conversation.
Which one of these is correct?
What kind of job is this? / Which kind of job is this?
Or
Which type job is this? / What type of job is this?
Both are equally "correct". The difference between them is very slight: to me, "type" implies that you are asking about where the job fits into some classification (which for some reason is known to you both), whereas "kind" does not have that implication, and is asking for any way you might want to characterise the job. But as I said, the difference is very subtle.
