What would you do if you were asked to perform a task and weren't sure how to complete it?

"Communication is key, so I typically talk with my supervisor and indicate that I don't understand the task. I ask questions until I have a better understanding of what is needed. If I don't have the ability or skills to complete the task myself, I speak with my supervisor to let him know. I also look for opportunities to work with someone who can make up for my lack of knowledge and possibly teach me a new skill."

Regardless of whether you know how to do something or not, it's part of your job to make sure it gets done. Your primary objective when answering situational interview questions should be to discuss a related experience and how you dealt with it in your previous job roles.
