Pros
Teleperformance is a great company to work for. As with any job, in order to be successful or promote within the company you have to commit yourself to show up to work on time and be willing to take feedback and act on it to improve. Teleperformance has many advancement opportunities and promotes from within. Compensation is fair and comparable to similar jobs. There are a great many things that have evolved and improved over the years because leadership does listen to feedback.
Cons
It's a face paced ever changing environment, and while that may not necessarily be a bad thing it may not be for everyone and every personality. I really can't think of any specific cons that I would call out because the company cares about feedback and does take feedback to improve.
