I'm currently interviewing for a web development job and so far every interviewer has asked to see my side projects/code samples. That's definitely a great thing !
At my current job (4y) I've been around a few languages/frameworks none of which were familiar to me when I took on the projects, but since our code isn't hosted as a service no one can actually see what the work looks like. I'm fairly confident I can work the "same" job on a new stack so I've also applied to jobs where on paper I don't have the experience they're asking for.
I can see how most of that looks like risk and unverifiable skills to potential employers, so I have a couple of side projects on Github. I spend a lot of time at my regular job which means I don't have a project for every language I plan to apply for and the ones I have tend to be technically simple.
I've thought about proposing to give me a sort of take home project as a test or to take me on for a trial period, but it comes across more desperate than confident.
How else can I convince an interviewer that I can learn to use their stack as I go ?
