The interview process will take several weeks. They usually call you after 6pm to keep you updated about the recruitment process.
There are several phases:
1 - Interview with the HR: the interview will be conducted in English probably so be prepared and train your overall speech in English. The question are very simple and straight forward - Tell me about yourself; Tell me about your degree; Tell me about your previous or current working experience; 3 defects and quality and how you manage them; they will eventually lead to talk about your leadership skills so make sure you you have a concrete answer like a position in a sports team, or group projects and give examples;
Then the interview will be more about them: Why Teleperformance (they are leaders in customer services (as they like to call it), you should reference that; why this program (LeaP management program) (you know best why you applied); you will probably have an engineering background and then they will ask "so why a management position".
And then it turns to you: when will you be available to start the program, do you have any questions? You can ask things like: what's the competencies that will make me a better applicant to this position - it will give you a perspective about what they really want in the candidates, and you can intervene to agree and tell why you have some (or all) the characteristics they are searching. You can ask about the salary, but no need to rush it.
2 - The next phase is some test, like 7 of them: numerical, abstract, verbal, English, motivation, personality, and mail management. Very straight forward, practice a bit, it will not harm you. HOT TIP: the absctract test will not have pictures, its like a figures Sudoku, so you can ace it easily;
3 - Group dynamic: about 4 candidates, they will give 2 case studies and give you initial time to read and then discuss it. The case studies are made to raise caos, so manage well the time, the objective is to get a mutual opinion about the case study, but that's not it, then they will ask you why choose that answer and not other, so make sure you get your facts straight. The case study is a call center reality, with quantitative and qualitative data, and you have to make decision about who will you fire (good start).
4 - If you get to this point, very litle can go wrong, its a panel of teleperfomance's employees and talk about yourself.
