I worked at Exelis (More than a year)
Excellent company to hire on with. Benefits package is excellent.
Turnover is fairly high but that is part of the intelligence community as a contractor.
I was contacted to do a phone interview where I was on a speaker in a conference room. Two Engineers, and two managers conducted the interview. I then came in for an onsite interview afterwards.
After the onsite interview I was contacted and told that I did not get the job at the time but that I was would be considered for another position. I was presented with an offer for the new position and accepted.
