The hiring manager is looking for validation that your qualifications and experience are in demand in the current job marketplace. Do not oversell your other opportunities because the interviewee may presume you’re holding out for a better vacancy. Also, you may appear like a desperate candidate that applies for everything.
Talk in generalities and don’t mention the name of a competitor company, as this could jeopardise your credibility some adverts are confidential.
A good response could be:
I’m very selective about the vacancies I apply for – and most jobs don’t fit my criteria. I have a couple of upcoming interviewers with top tier financial firms, for privacy reasons I won’t mention their names. However, I am very excited about this opportunity in front of me.
