Pros
Great training and experience from the start. Benefits are great too if you are able to make if in the company long term. If you are lucky to land in a position with a great manager with a clear career path with established timeline expectations, there is POTENTIAL for long term success and career growth.
Cons
In contrast to the Pros, career progression has slowed and career paths blurred. If your management is not straight with you on when and what role you will be working towards, get out. If there is a clear path and role, but then the timeline is missed for when that opportunity is supposed to start, get out. If you request to be transitioned to a new business (for example, R&D to Product Supply), make sure to ask if this will impact your career progression/promotion. If you join P&G in a position that is not where you want to be long term, be clear with your manager on making a clear path and timeline to that next role. Again, if the manager cannot make it happen or timings are missed, get out. P&G is set up to keep employees who are in roles they don't like uncomfortably comfortable the longer you stay, meaning you will dislike your job, but you can't leave because 1) you're tied to P&G because of the benefits, 2) you may be close to vesting, and 3) you can't leave because YOU'RE NOT GETTING THE EXPERIENCE IN A POSITION YOU WANT TO BE IN MAKING IT HARD TO LEAVE AND APPLY TO JOBS YOU TRULY ARE PASSIONATE ABOUT AND START ENTRY LEVEL BECAUSE OF LACK OF EXPERIENCE. If you can piggy back on the nepotism and favoritism that's rampant in the company, do it (everyone else is). Otherwise expect to wait minimum 15 years to get into a position worthwhile long term.
