F5 looks for the best. Not people with the right bullet points on their resume, but rather they look for people with an aptitude and hunger for learning. Most my interview questions were not product knowledge but questions that asked went in depth about advance technology concepts and also questions that made me have to think really hard rather than just regurgitating things from memory. More than anything else they were interested in seeing if I was a person that was constantly challenging myself to learn new things.
