R.R. Donnelley Presentation Designer interview questions

I had a telephone interview with HR in response to an ad I submitted a resume to. The second call was to set up the interview. I interviewed the following week with 3 managers at the client site. I felt as though the interview went extremely well. I met three managers, they discussed what I'd be doing, and even showed me the center where I"d be working. It has been six weeks and I haven't heard anything. At week 4 I sent a nice note thanking HR for the interview and asking for the status of my application. I have had no response - possibly due to the holidays - but six weeks is six weeks.
