Every company is different. I'm not in the IT field, I draw Construction Plans, House Plans mostly. But with that said all I have is a High School Diploma and I've gotten jobs that require a degree.
Some people apply for jobs hoping a company will choose them whereas I choose what companies I'm willing to work for. If you know your stuff anything is possible. My last job, before I started my own business, was the Architect's Assistant with a large home builder (500+ homes a year). I did my job and made the Architect look fantastic, she was crazy about me. But I made sure I had something impressive going on whenever the owner walked by. In 6 months time I was the in-house architect and I was hiring an assistant.
