I agree with @jr377 that in order to move up to the upper level positions, you would have to be promoted from a middle level position. Similarly, in order to move up to the middle level position, you would need to be promoted from a lower level position. I think I wouldn’t mind starting even at the lower management level but then over time with experience, I would want to move up to a middle level position and take on the responsibilities required for that such as planning, setting actions to implement company strategy in the most efficient way. I think this would suit me better than the upper level management because I’d rather be involved in these tasks.
