Did I sign a Non-Compete?

My offer letter from my current work contained this:

"This offer of employment is contingent upon your execution of a non-competition, non-
solicitation and confidentiality agreement, prior to commencement of employment. Employment
is also contingent on the successful completion of an FBI and PA State background check, as
well as a drug test. The general scope of the non-compete and non-solicit provisions will be 24
months following termination of employment and the non-competition area will be the
Commonwealth of Pennsylvania. Moreover, you will have a continuing obligation to protect
Company's confidential information."

However, I never signed any actual non-compete agreement with the company, and certainly not prior to the commencement of employment. My offer letter was the only place it has ever been mentioned. I am currently interviewing for another similar position, and want to make sure I'm in the clear.

Additionally, I'm not actually doing what I was hired to do; what my job description states.

I don't think that the non-compete will really hold up, I'm just curious if I'm correct.

EDIT: The quoted section above is from the offer letter, but no actual non-compete was ever offered to me to sign. In fact, when I inquired about the drug test, they just laughed.
