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 
If you're willing to really, really lie: You were a sick relative's full time caretaker during that time. You are not comfortable discussing the details, but they passed (and thus your future employer does not have to worry about you needing more time off to care for them) and you are looking to turn your skills into a more stable career now. Couple that with the lie about being under NDA for your freelance work, they won't ask shit
They’re still going to ask what you did for the NDA job. They’re expecting something like “I developed a web app for a client’s product that he plans on commercializing soon,” not “I was working on the new X-KNF high altitude surveillance system from DARPA. Specifically, I was developing the T-06 module on the lens.”
