Pretty simple. Got in touch with a partner, though a professor at my university. He told he was searching for a profile such mine and told me if I might be interested in an interview. I said yes and got a first interview with two managers (2:1) . The interview questions were easy, more oriented to understand my way of thinking than my effective business knowledge. After the first interview, I had another one with the client leading partner (1:1), and it went extremely well. He said me welcome straight away, and few days later I got the offer (internship at first, 4 months later turned into a full-time offer)

Campus interview at a business school in India. Two rounds of interview. Initial one with a manager - more technical, the other with a Managing Director - HR + little technical
