It's either that, how much prior experience you have in your given field or dumb luck. I got an associates degree in publications design & hypermedia technology and was unemployed for six months after graduating. Eventually, I just took a data entry position at the company I'm currently at through an employment agency and when the company took a closer look at my resume, they interviewed me for the vacant position in marketing and I've been here ever since.
Stay positive, someone out there needs a little Imgran in their life
