This one is among the favorites from the HR interview questions and answer list. This question is usually asked to check if the candidate knows how to do smart work as and when required. You can easily answer this by saying, “Hard work, in my opinion, is investing a lot of time in order to achieve a goal. Smart work, on the other hand, entails using more effective methods to accomplish one's objectives. I usually put a lot of effort into ensuring I satisfy my client's expectations when I know I have a lot of time to work on anything. On the other hand, if I am aware that something is due the next day, I work diligently to find the quickest solution."
