First round was with the HR where they asked pretty basic questions about my education, family, strengths, weakness, salary expectation, long term goals etc.
Second round of interview took place after a week with the Procurement department, where i was asked about my previous work experience and many other purchasing related questions.
Third round was with the Managing Director of the company, where we had a brief discussion about the job role.
I was offered the position on the same day and i joined immediately.
