MANTECH interview questions

I was offered a job at 2 other positions and had 1 where I did not make the interview and the second was scheduled. I scheduled at 10 am, at 5 pm that same day they canceled my interview and hired another person for that position. I went in for an interview on a second position, on a day that I requested off work. I had a great experience with the interviewers and was told multiple times they would love to have me and that with my qualifications was "over qualified". I did not receive the position.

Short if you know the hiring manager. Essentially, you likely know someone trying to bring you into the company for this particular role. I'm referring to roles dictated by a program.
