My current resume has a skill matrix, where I try to give a relative indication of how skilled I feel in the .NET stack.
In my current matrix, when indicating how much experience I have with a certain language or software, with some, I included experience from college as an indication of how long I've been working with that tech or software. For example, I say I have 3 years of experience with Visual Studio, with which I mean "1.5 years as actual work experience in a company, and 1.5 years of experience from my school assignments and tests". Should I include college experience in my skill matrix?
On a related note, my current skill matrix gives an indication of my skill from 1 to 5, with 5 being the product that I judge myself to be best at and the other languages and technologies being relative to that point. Is this how skill matrixes usually are made?
