Who was at fault doesn't matter. If friction sparked between you and your former employer, be honest about your differences of opinion, but avoid assigning blame or being hateful. If you harbor resentment toward a former employer, resolve your feelings and be ready to move on before you interview for a new position. Instead, it makes you appear dull, socially inept, or as though you are hiding something. Your personality is a valuable asset that you bring to a job - share yourself with the interviewer.
Relaxed candor is disarming, enthusiasm is contagious, and a small dose of humor is memorable.
Recruiters admit that they give an edge to candidates who demonstrate good people skills. Don't arrive late Scout out the agency's location ahead of time to ensure that you arrive five minutes before the interview. If you arrive too early, wait in the lobby, cafeteria, or another public area until five minutes before the interview. Your work habits will be called into question if you arrive late. Let the interviewer bring up the issues of salary, hours, and availability.
