as if that's their solution it probably could have been achieved comfortably in a two-week timespan,
I would like to add that even if something that can be achieved in a two week timespan as an individual, in
general it will take much longer in a big company.
As an individual when you want to do something you simply sit down and do something.
In a big company when you want to do anything, it would probably be more like the you go discuss with your team first then discuss with PM, have PM approve the budget, submit the budget to finance department and any other department involved, then the finance department will get approval from upper management, then they'll let the PM know so people can finally start doing the work.
After the work is done they still need to QA and notify community rep to discuss how to communicate with the playerbase etc. So that takes time too.
You also never know if those staff has other tasks to do before dealing with this task, or how much time do higher priority tasks need. Maybe they start the task a week or two later, you never know.
So I am not surprised that a 2 week task that can be done by a single individual ended up needing a month to accomplish in a big company.
Essentially using personal work experience to estimate actual time investment in a big company for anything will be difficult unless you actually know how this company works internally from a higher pov.
