Leidos interview questions

Applied through their website and heard back for an interview two months after applying. First of all, the interview had to be moved to the client site in Washington DC because of a meeting, which I did not mind at all coming, however, it was interrupted after 10 mins because the room was booked by another department, very unprepared and rude to not have a booked room for the interview. Interesting knowing about the projects and task but I think both people performing the interview were unprepared with question and they just threw at me whatever they could think of. The interview was 3 months ago, and to this date I have NOT heard from them at all. Very unprofessional and rude, even if they think I am not a good fit for the position I think I simple email should do the job. Very disrespectful to leave candidates like this without a response after an interview, doesn’t speak very well about the company and its employees.
