⟩ Tell me how do I ask for a business card at the end of an interview?
You should ask for the contact information of everyone who interviews you. The information can be in the form of a business card, if they have one. If not, you can jot down names, mailing addresses, phone numbers, and email addresses. You can ask for this information as you conclude the meeting, or you could potentially ask for it at the beginning. In regards to your own business card, you should offer it at the beginning of each interview or individual meeting.
