The recruitment process itself is rigorous. You have to be called for an exam first, and I remembered there were 4 levels for just one part of the examination. If you fail on 1 level, you will be asked to leave the room and obviously you didn't made the cut (They will approach you to tell you this, so you don't have to be worried being called out by your name to leave). After this examination which will be held in 1 room, you will be asked to have a phone test which an automated call will asks you different questions. Then you will have a reading comprehension exam, and after that, an interview with the HR. They will call you again to come back for the interview itself with the team manager and other bosses of the division you are applying. That's the last part and you will therefore get the result after.
