So I'm currently employed at Company X and want to get out. I've applied at Company Y and have had a bunch of success - they're very interested in me. Company Y is a client of Company X. This shouldn't be an issue normally, especially because I actively applied for the opening and it was done through a recruiting agency and I didn't know it was Company Y until further in the process, meaning that Company Y cannot be at fault for poaching employees in any way. Anyways, I lied about my start date at Company X (I said June 2010 instead of June 2011 - yes I've only been working here for under 6 months). I told them they don't have permission to contact my current employer because it could jeopardize my current employment situation. I strongly believe that lying about this allowed me to get my foot in the door and that I would not have been able to otherwise. Both myself and the prospective employer agree this is an amazing fit. I was recommended to lie about this by my dad who has been in management for decades and said it shouldn't be a problem. Now I'm sort of freaking out. I'm worried that they'll offer me the position, I'll accept and quit at Company X, then they'll check my date of hire after offering me the job, discover I lied, not believe me when I exhaust one of two options - insist I've been working there since 2010 or claim they misunderstood and I always said 2011 - and recant the offer or fire me, depending how far along in the process we are. This is pretty much worst case scenario but what is the likelihood of this happening? I'm sort of starting to freak out about it. Was it a dumb idea or actually smart to do?
