Don't do that if you're in the US. I was laid off and finally got two offers, both places ran a background check and had all the information - my previous title, precise start - end time, etc. I've talked to one hiring manager and he told me that they had a lot of offers revoked due to failing these background checks recently.
Wouldn’t be the first time I “lie” in my CV about my skills (“lie” in quotes because I can learn pretty fast; I know the fundamentals)
