Ventajas
Policies on safety (some are way too much though - Example: you are not allowed to drink a cup of coffee sitting at your workstation)
Desventajas
Service company leads/managers with no people management skills. They behave like school head masters, not even an iota of respect to lower level employees. These managers/leads jumped into this centre with the advantage of being earlier worked for Shell clients. Not a secure job. Hire and fire is the norm here. HR hiring to meet the target headcount with no intent. No promotion until completion of 4 years. And more importantly you have to either look out for a new role or leave after this 4 year period. You will be hired for one thing but in reality you will end up doing something else and in worst case night shifts. Extremely bad life-work balance No per diem for travel(if there is one) HR is awful. Professional ethics/responsibility doesn't exists in their dictionary Cafeteria food is pathetic to say the least. Bad CTC structure. No tax saving options.
