When you are creating your resume, you don’t need to put every random job you’ve ever had. What companies do is they look at your jobs on the resume, and at most call the employer and ask them if you worked for them and how you did at the job.
There is no way for a non government employee to know if you worked other jobs. Keep off any jobs that you worked at for less than 2 years and use every skill you learned as a skill for your resume.
Nothing hurts your resume more than having 3 or 4 jobs in a span of 2 years because it shows you are unreliable.
I can see that for a security role… maybe. It would have been a massive waste of time and money for what we were doing, though. Plus, this was during the good old times when people weren’t being fired left and right. If anything it was hard to find people with the right qualifications that were still available. People in the field were getting hired directly out of school. If you could pass the tests, do the job and not act like a psychopath during interviews there were very few things that would have disqualified you.
I’ll also say that I’m pretty sure some of what you describe would have been illegal over here, at least for most jobs.
