Pros
Great co-workers and good opportunity for advancement for those who are driven to succeed. You will become very, very good at your duties regardless of your position within the company. The company actively mentors and trains its employees and does not tolerate laziness or apathetic attitudes. They promote heavily from within the company and seldom hire externally for upper level positions.
Cons
Not fairly compensated for position or amount of work demanded. There is a saying that you can not squeeze blood from a rock, but with Teleperformance, they found a way to do it. If they force you to squeeze a rock hard enough, your hands will bleed all over it. Hence, a bloody rock. The company pushes its employees to the breaking point without market equivalent pay for similar jobs. The company emphasizes to employees the opportunities for advancement as they promote heavily from within the company and seldom hire externally for upper level positions. What they don't mention is that nobody outside of the company is interested in applying for those positions because they pay being offered is usually 1/2 to 2/3 below market value for similar jobs.
