Had an interview for a promotion at work and got through the first round of interviews. After the first round it was down to me and a colleague. During the gap between first and second interviews an external candidate applied 2 weeks after the deadline. My colleague then dropped out and left me and the external candidate. Got the news today that they have gone with the external. I'm really pee'd off as I've been stepping up into the role for 2 months and received brilliant feedback. My line manager said he would understand if I were to look elsewhere for a new job.
