The division I used to work for was combined with other divisions and renamed.  So there is absolutely no reasonable point of reference I can give my prospective employers to check up anything about me.  I figured the best I could do is give them the HR department of the corporate headquarters, in D.C.  So I went to the website of this very large, multinational IT company, and from there spent over an hour trying to find a phone number, ANY phone number, for this company.
