You get hired in response to a lengthy job description, where pretty much you have to know and do everything ever related to project scheduling.
Just to find out that the people who prepared it do not have a clue about most of it. If a skilled person, and willing to work, and help (and many, from field bodies to the management, need a lot of help), you will end up working 100 hours a week, and quite likely get only insults in return.
They have "systems", but then you realize that hardly anybody follows them. Like Roman ruins. Used to be nice structures, once upon a time.
Arrogance and narcissism prevents many from learning, especially many of those adorned with title which includes word "manager", as if that included an instant brain transplant with all the skills included.
But, you will be the one who cannot win, when their big gaps become obvious.
Schedules are run (activities created, not to be modified) in a package separate from P6 (without any consulting with schedule control) by people who do not know scheduling or projects, and not even the estimating or the cost control which are supposed to be their specialty.
Job description wants you to build from that schedules "which will facilitate delay analysis", but you are not allowed to add non-Cost Control activities which are needed to create the logical network.
Lots of data from cost control is transferred into P6 through Excel, by people who do not comprehend the basic formulas, and many times resort to typing numbers over formulas, in order to "make them fit".
All in all, large mess and disarray, with lots of denial.
And those who work right can only get hurt.
Two people a week were leaving in my time there. Judging by continued job postings, that pace has continued through 2026, at the same area.
