The interviewer is testing your depth of knowledge on ResMed and their products. How you answer this question will quickly reveal to the interview how much, or how little, research you have done before the meeting.

Start by researching the company website and look for any special mentions. Generally, a company will highlight their best seller or most popular product. Next, Google search the company name and see if any particular product comes up in your search. Lastly, check customer or client reviews to see if there is a consistent theme.

Give your answer by demonstrating your research, and logically backing your answer. You should ask the interviewer what their best selling product is, as well. This question could open up a great conversation between yourself and the interviewer while providing you with additional information that will be helpful for any upcoming interviews with ResMed.
