Employers don't care very much about what is on paper. Got an MCSE? Great! But can you actually put it to practical use? A lot fail right there, frankly.

But mostly, it depends on your abilities to solve issues using your intuition. For example, how would you answer this question if your potential employer asked this:

"How many gas stations are there in the United States?"

If you'd answer "Thousands" then you're automatically scrapped. Why? Because you guessed... You're not supposed to guess, but to put more thought to it, collect more data and try to solve it with better accuracy. That will make you a more dependable employee.

So you'd answer that question with a counter question, like "What kind of gas stations?" (more though, collect more data) and/or an indefinite answer like "I would have to look that up" (solve with accuracy).

Your experience in the field will help you answering such silly questions.
