My first interview was with a senior consultant of the firm. He welcomed me in the room and introduced himself. The interview started with “Tell me about yourself” question. I gave him my answer and he asked some clarifying questions about my work experience. I had an entrepreneurial experience. Interviewer asked me some basic question about the business and then asked me about the market size of my business. I calculated the market size basis on the number of households in the vicinity. He did not ask me any other guesstimate. He finished the interview after giving me a chance to ask questions.
