What They Want to Know: The interviewer wants to know why you're an excellent fit for the job. Try to answer questions about yourself without giving too much, or too little, personal information. You can start by sharing some of your personal interests and experiences that don't relate directly to work, such as a favorite hobby or a brief account of where you grew up, your education and what motivates you. You can even share some fun facts and showcase your personality to make the interview a little more interesting.
Start by explaining what you'd need to do to get ramped up. What information would you need? What parts of the company would you need to familiarize yourself with? What other employees would you want to sit down with? Next, choose a couple of areas where you think you can make meaningful contributions right away. (e.g., “I think a great starter project would be diving into your email marketing campaigns and setting up a tracking system for them.”) Sure, if you get the job, you (or your new employer) might decide there’s a better starting place, but having an answer prepared will show the interviewer where you can add immediate impact—and that you’re excited to get started.
If you are currently employed, you should be honest about the start date and show professionalism. You should tell them you would have to discuss a transition with your current company to see if they require a two-week notice (or some other timing). If you currently have a critical role, your potential new employer would expect a transition period.
