The interviewer wants to know the areas you struggle with, but they also want to hear how you manage that struggle. This can be school or work-related. You can be candid in your answer, recognizing that you aren't great at something and acknowledging your need to improve. However, pick weaknesses that are not core skills for this position. Be sure to have an action plan in place for improving on this weakness.

Perhaps you are watching TED talks to gain skills in a particular area, reading the latest and greatest book on the subject, or maybe you are taking a seminar at a nearby community center. Identify your weakness and the action taken for improvement. We are all human with our weaknesses, so don't be afraid to share yours!

"I believe I could improve on some technical skills including Excel and PowerPoint. Currently, I am somewhere between beginner to intermediate level. However, I would be more comfortable at an advanced level to help me develop more effective reports. I have enrolled myself in an evening/weekend workshop for the next six weeks. I'm looking forward to seeing how stellar my skills are after that course and how I will be able to apply my skills on the job!"
