Now, again, this is a trick question. Do not use the word 'hate' right away. Instead, replace the word with 'challenging' or 'difficult.' As you are obligated to complete any given task, you cannot simply dodge it just because you don't like it. You need to stay focused until you arrive at a proper solution. If that seems complicated, question your client as much as required and discuss with your team members to build a strong base. The response could be like: There isn't any content I particularly hate. With the help of mindfulness and communication, I often break down the complexity in the toughest of projects. There must be copies that I didn't absolutely love, but I somehow manage not to hate them." This sort of response will make HR realize that you are an optimistic individual and you own the skills to deal with every challenge in life. That forms an excellent report on your application.
