Xerox Business Analyst interview questions

The project I was currently working for was coming to a close, another project was looking to gear up for completion. My resume was submitted to the hiring manager and shortly after submitting the resume an interview was scheduled. The interview was a teleconference with hiring manager for position regarding transition into new project from current analyst position. From the close of the interview the hiring manager confirmed the position that would be offered and that an offer letter would be submitted to me shortly. three months later no offer has been submitted.
