This thread has another 2 instances that confirm this.
Being suitable for a managerial role versus a technical (analyst) role boils down to the different job levels requiring different sets of skills.
If you really want to make the move, I think you will have a better chance if you can get your current employer to give you that opportunity than another company.
Good Technicians (Analysts) rarely make good Managers and asking another company to give you that shot to make the jump is in my opinion, a waste of your time.
If you are looking outside to make the move, I think it is rational for a prospective employer to think you are disappointed with your current work situation. If that's the case, maybe you will move if given the right things. Could be better pay, shorter commute, awesome cafeteria, new environment, etc.
I can understand being frustrated with the "bait and switch", but I think if you realize that the different job levels require vastly different skills ..... you should realize that you never really had a shot at the managerial position.
I mean, do you honestly think an analyst position and the manager position require the same skillset to be successful?
