I completed my 4 years bachelor degree in engineering in 9 years. In this extended duration I was working freelance designing for different construction companies. In fact, I probably was making more money than my peers who got jobs after completing graduation in 4 years. Now I have acquired a degree and have a design and software experience from my freelance work.
How can I convince my potential recruiters that I at least have 3-4 years of countable experience through my freelance work?
