Dear Manisha Thakur,
While the previous member has shown courtesy to upload a list of the questions that can be asked in the interview of "Business Developer", I prefer to ask a few fundamental questions.
What is the context of your query? Are you an HR professional and if yes, then will you conduct the interview for the post of the business developer? Has the Job Description been prepared for this position? If yes, then is it not sufficient to understand the role and functions of the business developer?
Who is eligible to conduct a job interview? Only an expert is eligible. Therefore, the situation merits self-assessment and one should ask a question, am I sufficiently competent to assess the suitability of a job candidate? While an ignorant interviewer can take a job interview, the cost of the wrong hire could be far higher because of the customer dissatisfaction or other operational issues.
Thanks,
Dinesh Divekar
