- the applicant worked for one of the big four (Google, Apple, FB, Microsoft). If these companies gave the applicant a GO at some point, maybe you should too.
- the applicant is self-driven and develop non-work related software. Side projects, etc.
- the applicant brings new skills on top of your requirements (e.g. design, other industries, mobile, etc.)
- last but not least, you should value the experience a lot. Someone who worked 5-10 years on a bunch of different projects will save you a lot of time and money. You could have a genius/fresh out of college, if something goes wrong or requires certain skills they don't teach you at school, the lack of experience will drag you down. Don't hesitate to pay a premium up front and save money in a long run.
Good luck!
