Let me be candid. I have worked as a software Engineer all my career with 2 years of product management experience (did a startup 4 years ago). I wanted to switched to PM full time but was not getting calls due to lack of experience.
Since I am very confident in my PM abilities, I decided that I pose as a PM in my current company, upped my experience to 4 years on my resume and started interviewing and I got job offers almost immediately.
I know I lied since I did not get any interview calls for many months and did not see a way out. But I am now afraid of the background check. All other details like dates, salary, other employment history is correct.
