This question is meant to elicit comments about any hesitation you may have about the position. It provides you with an opportunity to redefine the term used by the interviewer and answer the question in a positive manner, such as using the word 'challenging' in place of difficult. State that a particular aspect of the job is challenging, but that you enjoy challenges and work extra hard to overcome them. Some of your greatest successes have come from challenges because they present opportunities for development and self-improvement.

"One of the most challenging aspects of my job is staffing. Network Security Engineers are in high demand. This has resulted in both a shortage of skilled people and the labor pool being populated with credentialed engineers whose training and skills don't match their credentials. I've overcome this by leveraging my network within the industry to identify viable candidates. I then put them through a rigorous interview process to verify their skills and experience. Finally, I've created a program within the organization which provides them with training opportunities and a path to promotions with more responsibility if they meet our strict performance metrics. This has resulted in us being able to both attract and retain the talent we need."
