Sandia National Laboratories interview questions

I had a two day interview and met with a total of 15 people and gave a presentation based upon my Ph.D. work. The interview was very relaxed, most people asked me what questions I had about Sandia and about the city. I only got a few questions based upon my presentation. Besides that, there were no technical questions. Most of the time during the interviews was spent with me asking the interviewers about their research.

Met with 5 interviewers that day all asking about my background, what I did over the summer (I was just fresh off an internship with them), and asked if I had any questions. Not really any technical questions, all were personal queries. Interview also consisted of a free lunch. The hiring manager said to expect a decision to be made by the next month. Here I am 4 months later left hanging, wondering if they even care to finish the interview process. I even emailed the hiring manager twice. The best I ever got was, "corporate still hasn't released the amount of candidates they could hire, we'll get back to you later". Not cool.
