Didn't U read fine print on the application? That's no no.

All security clearance applications are under scrutiny by gov agencies and field agents/interviewers. And unlike other job applications, it is federal offence to mislead and provide untruthful information which may lead to jail term. You can do whatever you want on other applications but never lie when dealing with clearance. I've been ask specifically on the cause of leaving for each of my previous jobs. And they did call the employers and also verify the position via company and income tax records.
