Some recruiters might ask you for certain sensitive data like age, marital status, nationality, that might not have any apparent bearing on the profile you have applied for. However, the job might have specific requirements in these areas.
Here is a list of questions that are generally considered avoidable for an employer to ask of an applicant. These questions are provided for your reference and they need not be answered.
If you are asked one of the above-mentioned questions, and you want to work with the company without compromising your rights, you could respond with a counter question −
“I’d love to answer the question. Would you mind telling me the reason for asking it?”
The applicant must note that the interviewer can still obtain these details by asking these alternative questions mentioned below.
