The interview itself was fine. Three people asked mostly technical questions in a conference room. It was a fairly comfortable setting. However, after the interview and offer this company was a disaster. The position required an interim clearance, and when it didn't go through, the job offer was rescinded. I asked if I might still have the job if/when my clearance did go through completely, and the only answer I ever got was "I'm not sure". Later, emails went unanswered but the clearance check continued! It's been months later now, I have another job (that I'm very happy with), and still no final word from anyone at COLSA. I don't think it's very nice to leave someone's life hanging like that.
