Is a little white lie a big black lie?

So, I work for a company and I got an offer for a higher paying job within the company and I have the educational experience for the job. So, during the interview, I told them that I was still working when I finished my two weeks four days prior to the interview. The company called my boss and my old boss approved my transfer. I found that out on my first day. I'm still awaiting my final paycheck. What do you think of the chances that I'm screwed?
