Which department? If you are in finance/IT/HR/credit control, schlumberger implements shared services.

If you are going to shared services...its a different ball game. If you are a guy, you will find working in shared services very boring because its dominated by see lais (housewives). One thing I can assure you is that shared services is very efficient unlike the other commercial companies, once you finish a role in 3 years, the company will move you around inter department to increase your job exposure and won't make you get bored.

The only downside is yeah as I say, you will be surrounded by aunties. I hate working with aunties, their brains not flexible enough, no.1 office gossipers.
