"I believe I could improve on some technical skills including Excel and PowerPoint. Currently I am at a beginner to intermediate level; however, I would be more comfortable at an advanced level. I have enrolled myself in an evening/weekend workshop for the next six weeks. We will see how stellar my skills are after that course!"
"My primary weakness in the workplace surrounds my technical abilities. I consider myself a beginner level user in Excel so I have decided to start a course this fall to expand on those skills."
"Everyone has weaknesses. I tend to be too nice sometimes. When vendors are not fulfilling their requirements, I tend to believe there must be a logical and understandable reason. I have to remind myself that we are paying for a service and they must meet our expectations."
Sales answer example
"I know this will come off as cliche, but it's truthful. My weakness is in not delegating. I know what I want done and how I want it done, so it's often easier to do it myself. However, it can inhibit my ability to grow. I cannot take on every step of a project, I need to be able to give the task or a portion of it to another team member or direct report, let go of the control, and know it will be taken care of. I've spoken with my current manager about it and we've developed a system where he can call me out on the behavior, since often times I'm not aware of it. By bringing awareness to it in the moment, I find my propensity to hold onto control has decreased, so I'm certainly moving in the right direction."
Retail answer example
"I would say the area I need to focus on improving would be my IMS proficiency. I am proficient, and it does not hinder my ability to do my job successfully, but it's certainly something that I need to work on improving, and am always asking for other managers to show me their shortcuts and tricks of the trade."
Teacher answer example
"I'd have to echo my boss and say I need to spend less time bucking the system, but I really feel it is in advocacy of my students. I suppose not resigning myself to it is a bit of weakness. It's certainly something I struggle with, coming to terms with the educational policies with which I disagree. I try to walk the line of advocating for my students, and future students, while being sure to be respectful of the administration and educational system as a whole."
Marketing answer example
"I believe my biggest area for improvement is in my software proficiency. I have a working proficiency of Illustrator, InDesign, and Photoshop, but it's not as strong as I would like, so it's something I'm constantly working on improving. I have watched a lot of YouTube videos about it and am always seeking the advice of my graphic designer friends, so it's something that's a work in progress for sure. I hope to be much more comfortable and confident, as well as efficient, in my use of those three programs by the end of Q1 next year- it's a personal goal I've set."
