Pros

Clean office and good cups of tea. Girls at the front desk also very pleasant and helpful.

Cons

Office is extremely quiet with no atmosphere and staff are treated like work horses or even dogs. If you attempt to challenge a decision you will find yourself Infront of one of the so called managers who will threaten you with your job.
