My recently graduated sibling had an interview this morning. Apparently she has been asked the titular question during the interview. She answered it like "No worries, since I will be continuing my master's program, it means I'll have more time to continue my studies without compromising work."
She has been a very hardworking student with a pretty good GPA, in addition she spent her last year doing part-time internships where she acquired the skills the company she applied offers long-term training programs for.
After the interview when she called me, I told her she should have answered it with something like, "Every job deserves to be taken very seriously. Even if you think my skills are above the requirements for this position, I think this will provide me with an opportunity to take more responsibility where I can utilize my experience."
Now, I know that a lot of the companies in my country ask questions that put the spotlight on the candidates, in order to "test" their humility (I know, pretty stupid, but humility is a part of the workplace culture and that's how it is). But I wonder if there could be a better way to answer this question again when (and if) she's called for a second interview.
