I'm not sure about that. I started programming some 30 years ago, and wrote quite diverse programs, but not always professionally. I've been working professionally some of that time, of course, but in between jobs I've been doing my own things, which didn't translate into a commercializable products (but some could some day, I guess) and I keep them out of my resume. Jobs always found me, not the opposite. So I don't have much experience seeking one.
But these last two years I did try to look for one, every now and then. All in all, I sent my one-sentence-per-job resume to about 10 companies, which I researched somewhat thoroughly and concluded that can put my skills into use. I know it's not the usual shotgun approach of mailing zillions of companies in hope that one will turn out to be The One, but that's how I work. Friends and family tell me that I should put more into the resume, but I'd rather explain stuff face-to-face. Of course, I don't get there. I'm also very picky (my ethics filter out so many companies, you know, tracking people, advertising, etc..). Anyway, out of those ~10 companies, only 3 got back to me. One of them rejected via email in a matter of hours. The other two had HR call me. One of the two invited me to a face-to-face nontechnical interview with a young manager... not the position I've applied for, but anyway. It was friendly though kinda stuck at why I decided quit some company 7 years ago. She might have also found me clueless, since I didn't have a formulaic conception of software development that she seemed to inquire about. The next day I got an email rejection.
Now, I'm a very technical person, and I'd probably have more success going via a different route, maybe meetups. I'm an introvert, but don't have difficulty opening up to other technical persons. So I'll try that. (No LinkedIn or "networking"... a privacy-conscious introvert).
But anyway, my point is that I projected a high probability of providing good value to these companies after nontrivial amount of research into them and their positions, but it seems they're all drowning in noise so manage to miss my signal. Industry situation is poor.
Luckily I'm keeping to my own projects as well. Some day they may bear financial fruit.
