I graduated with a bachelors in computer science around 4 years ago. Long story short, I was depressed, dysphoric, and suicidal throughout my college years and by the time I finished I didn’t want to do anything. I’ve been unemployed for the last 4 years but I’ve also transitioned, started taking better care of myself, and overall I feel much better.
Anyways, I need to get a job now. What kind of lies can I get away with on my resume to cover up the long period of unemployment? Should I pretend I started some sort of company and it failed? Pretend like I went on some backpacking journey in a foreign country? Do companies even check all this stuff?
I did do an internship at a big tech company several years ago, and I’m working on personal software projects so I can put that on my resume. Also, I’m in Amerikkka.
Sorry if this question has been asked here before 
Lie if you like. Don't lie about things you could be asked to do. Like if you say that you were in charge of doing a thing, as interviewer I may well test that.
As interviewer I don't or shouldn't give a shit about your history except to try to predict your future. If lying gets you past HR to get looked by the hiring manager, AND the hiring manager thinks you're a reasonable candidate for the role listed, then that is a win.
Good luck!
