其实不奇怪, 人家觉得你是可教之材

They will interview you as long as they feel you have the right attitude and is a quick learner.
IT job is a skill job, not degree.
Experience can be learned quickly through the experienced people.

Plus if they can not find those people with 2-5 yrs experience, Or, if those guy don't want their salary, then they have to find you.

C# developer may not be the bst interesting job for you, it was not for me either. I like database stuff, it is easy to learn better life style and realy EASY MONEY. (this is what I heard from many people who did successful transfer from the useless ??? major to Oracle)
Thanks!
