put fake experience,tell truth in interview

Hi all,
For the past 1 year, I have been trying for job in SAP as a fresher, but no calls,no interviews.I know showing fake experience is unethical, but i dont have any alternative.After showing fake experience now iam getting calls,but still i feel guilty.Friends i have some questions.
1. If suppose i tell the truth in interview that i have shown fake experience,what would be the interviewer's reaction? Will accepting the fake go negative against me?
2.Whether i should accept the fake in technical round itself? (or) Maintain the fake,prove myself strong in technical round &then accept the fake in HR round?
3.Some of my friends(who have shown fake and well settled in MNC's ) are telling that during interview u should never accept as fake i.e., u should act confidently as a real experienced guy.Even if the interviewer come to know that u r a fake guy, but seeing ur confidence level ,he/she will select u ? Is it true?
Friends, particularly interviewer's , HR's please give me ur valuabe solutions.Other's suggestions are also welcome.
