The best approach to answering this question:
The ideal answer is to choose an element of your work tied to the position you are interviewing about which you are truly passionate. It should be something that naturally excites you, elevates your level of presentation and causes you to naturally show the body language that this is something you truly love doing (leaning forward in your chair, smiling while speaking, more animated speaking, etc.). If you want to excite an interviewer, get them excited about your passion for your work. If you're having trouble identifying an area for which you are truly passionate, think about that story you brought home from work where you saved the day, where you did something that no one else was able to do, where you were the superstar. This is your opportunity to shine as a superstar. However, be careful not to choose an area that is so limiting that it is a very small percentage (or perhaps no percentage at all) of the work for which you are interviewing. Also, try not to make the entirety of your ideal job focused on one minor element. For entry level, tie in a key aspect of your education or recent internship. The best way to answer is to start with the phrase, "My ideal job would involve…" and then go on to talk about that element as a component of a larger job, rather than the job itself.
In my ideal work environment, there would be lots of collaboration with like-minded individuals and high-functioning tools that enabled our success . We would sharpen each other to become better individually, allowing us to exceed our own personal goals for growth. We would also have the individualization to manage ourselves as small business owners in a sense, complete with flexible time management and a personal commitment to our customers’ satisfaction. This type of environment would be ideal for me because while the process is group and company centered, the rewards are personal and deeply fulfilling. Compensation is more than just money; it's contentment, satisfaction and having pride in your work. It's the ability to have mental freedom. – Blakley McCaig
