Assure the interviewer that the challenges you look for in a position are ones that will push you to grow in your career. Interviewers want to see that you are never complacent and that you like to set goals for yourself. Also, if you have read the job posting, you should address the challenges present in this role and how they align with what you are seeking.
"I am looking for a position where I can better exercise what I learned while earning my CPA. My current position has simpler accounting concerns, and so I seek to join an organization, such as yours, where I can be part of more complex accounting projects."
"When I read your job posting I was thrilled to see that you are looking for an expert in Excel as well as someone with training and onboarding experience. I have been seeking a role with further opportunities in leadership and also on the technical side."
"As an experienced manager, I am looking for the greater challenge that comes from leading a larger team. I currently manage 15 people, so my interest was piqued when your job posting mentioned a team of 28."
"I have worked as a freelance marketer for many years and seek the challenge that comes from working for a larger agency with enterprise level clients. Your company has been on my radar for quite some time, and I would be thrilled to join your experienced team."
"My previous role offered part-time hours in a non-commissioned environment. Now that I have completed my business degree I would like to join a company full time, in a commission driven environment. The challenge of meeting a sales quota is exciting to me."
"The quotas in my current role are quite conservative, and my client list is warm and primarily full of long-time clients. Now, I seek the challenge of further business development activities, a more aggressive sales quota, and hotter leads."
"As a teacher, there are always challenges in the classroom. What I am seeking is further professional development opportunities. When you mentioned in the job posting that professional growth is a significant focus in your school that was very appealing to me."
