Pros
The name recognition can enable more successful relationship building with customers, partners and even potential employers. Experience with the processes and procedures of a global corporation, which while arduous at times, can be a valuable skill to learn when navigating larger corporations. Flexibility in some positions on personal time, as HR does not force micromanagement of employees time. Ability to move around to numerous roles and organizations without ever leaving the company.
Cons
Too large and too impersonal. Corporate culture does not realistically trickle down to management level. Claims of pro-woman, pro-family is all marketing hype. The reality is that HR is ineffective and each business unit is run however that management chooses to run it. There is not a lot of incentive to be a super star or overachieve (recognition, compensation, career growth, etc…). Being a People Manager can be painful and time consuming, as the processes are never ending.
