Here’s a tricky one: How much does the HR manager need to know here?
If you admit to having interviews with other companies, it might look like you’re not 100% dedicated to this one.
On the other hand, if you say you are not considering other positions, it might make you seem like you don’t have other options (and the company has the upper hand in salary negotiations).
The right way to go about here is to find common ground between the two answers.
The interviewer is probably asking because they want to know whether they have competition in hiring you. They also want to know if you are serious about the industry and are legitimately looking to be employed in this field of work.
If you do have other interviews lined up for other companies, express that you are keeping your options open but that you favor this job in comparison to the others.
Don’t have many other options? Stick to the same approach.
Whatever you do, don’t make it seem like you’re desperate or that you don’t have any other options.
I have had two interviews during the past week with companies in X and Y industries.*
However, as I’m very passionate about both your industry and the work you have done during the past several years, I am more inclined toward working for you, if everything works out.
