With management trainees, you can have a few paths. Firstly yes you do get exposure when moving through the various departments but what you might fail to see is that they are moving you through these departments to find where you are most suited. So if you are stuck in some department, what is the difference if you are an engineer in another department as well?

Secondly with management trainees, you might not have the necessary qualifications to even make manager for certain departments. For example, if you are placed in the accounting department, they might not promote you due to your lack of qualification in the accounting field.

How sure are you that this is good? Have you actually been in that position? I know for a fact that it is totally not a management trainee progression whereby you would be moved from one department to another. They will streamline your abilities via a series of tests and interviews before putting you in a department. And from there on you will start building your career there rather than going through the various departments.

Again becoming a management trainee does not teach you to be a businessman. You may learn one or two things but that depends again on which department you might end up in.
