This seems strange to me. The market for engineers is really, really competitive right now. I know we're struggling for applicants - to the point where we've started reaching out to people rather than expecting people to come to us. We're certainly not going to immediately pass on someone who applies with solid experience, especially if they have multiple personal projects that demonstrate skill.
It makes me wonder if there's something else going on here. Are you applying to positions that aren't a good fit for your experience or skills? Like only applying to senior positions when you've only had a few years in the industry or only applying to positions in languages you've never worked in (but want to) ?
I really struggle to believe that sharing code from personal game projects or music tools would hurt (rather than help) your application. (Unless, as mentioned in my other comment, you really cut corners in those personal projects.)
Edit: I see, reading your other comments I see you mention that you're in a receptionist job right now and I think that resolves my confusion. If you don't have any actual work experience, yeah, getting that first job can still be really hard. Everyone wants senior engineers, no one wants to hire juniors. Which fucking sucks, because we have to hire juniors for their to be seniors. But, again, putting good code you've written - even games and music tools - should help not hurt you. So I would examine the code you've written for those tools and make sure it is good, solid code. If not, take some time to clean it up and then try again. (If you can find that time.)
