There are 0 good reasons for ever telling an interviewer (whom you likely JUST met) where else you are interviewing.
First, why is that information relevant? Interviewers should be focusing on their own companies and instead of worrying about your other potential opportunities.
Second, many industries are smaller than they appear and you don’t need anyone speaking to other people at other companies; possibly disrupting your search.
Third, it’s simply none of their business!
If you are asked this question in the future, simply state “I’m actively job searching,” and leave it at that.
Often, questions like these are used to gauge how fast a company will need to make you an offer or how aggressive they will have to be with a salary.
The content of these interviews (business meetings) should only be about your skills and experiences as well as the role and what your responsibilities will be so both you and the company can decide if the opportunity is a mutual fit.
