The problem in CX is not usually the seniority, it is getting accepted for a command course in the first place AND passing it. If you do not meet the expectations of our valuable ' training ' department, the time to command will be ... INFINITE, you will be simply stuck, without any career perspectives.
I am sure everyone within CX is aware of that, however, if this thread is meant to be as an information for potential new joiners, this should be taken into account when making the decision. ( I, unfortunately, wasn't so clever)
