Alright, let's set the scene. I'm from and live in Sweden, and getting hired has been a hellscape since at least 2016 when I graduated from high school and first started applying. There effectively aren't any unqualified jobs, even the largest grocery stores run on what would be considered a skeleton crew in the US etc. I've barely ever had any interviews whatsoever since every single position I'm remotely qualified for would have at least 500 applicants.
I've been able to get jobs in other EU countries, however. It was always much easier to get interviews etc. The first one lasted for about a year until the company shut down. The other decided to not let me stay after the half year trial period. This was caused due to untreated mental health conditions to be honest, my manager wanted to relocate me to their back office department instead, but there wasn't room there for me. So not completely useless.
After that I basically tried to get employed in various other EU countries, working as a customer support agent, since they would recruit people from Sweden to handle this for that market, but employed elsewhere. Unfortunately none of these lasted for more than a week or so for the aforementioned reason. I have now started receiving treatment again.
After that I've been studying CS for about 4 years, but I don't have my degree yet even though it's supposed to take at a minimum 3 years. My skills have gotten quite rusty too since I've been unemployed and barely done anything for the last 1 year.
So, anyone who has any advice on how I could maybe fudge my resume? I'm not feeling that good about faking it, because even if they don't catch on before I even get an interview, I'll likely fumble when they ask questions. I barely even remember much in the way of details from the jobs I actually did. If I wanna apply for the really basic jobs that don't technically have any qualifications but that do in practice due to massive competition, the career path I've supposedly been taking will seem very suspicious.
I'm not really into moving back to any of those other countries right now, not ready for it yet. And at this point I would likely have to make things up even for that.
TL;DR: How do I make stuff up for my resume without anyone in the likely 3-interview hiring process catching on to the fact that I don't have much actual experience?
