PwC Interview Question:

Interviewers ask personal questions in an interview to “see if candidates will fit in with the culture [and] give them the opportunity to open up and display their personality, too,”. In other words, if someone asks about your hobbies outside of work, it’s totally OK to open up and share what really makes you tick. (Do keep it semi-professional, though: Saying you like to have a few beers at the local hot spot on Saturday night is fine. Telling them that Monday is usually a rough day for you because you’re always hungover is not.)
