At the end of 2016, I was contacted by Patricia T*** / Celia M*** from Rolland Berger, Sao Paulo's office, to have a round of interviews with 2 partners. Few days later, we scheduled another round of interviews with 2 other partners. Since then, I never heard from the company again. Asked twice for a feedback, no answer at all. In short, if you are applying for a position at Rolland Berger do not expect respect from them, at least from the Sao Paulo's office, and be adviced that you may never get a feedback.
