Tell me about your greatest work-related accomplishment.

"The greatest accomplishment in my career was graduating from University as an honors student while working full time in a related field. I was at the top of my class and working full time. This success showed me that I could dedicate myself to my career and reach the goals that I set for myself. It felt great to accomplish so much and receive recognition for my dedication."

"I am most proud of being selected to be a mentor to new hires in my current department. I think I've informally mentored and exhibited leadership since day one, and to be recognized for being a great teacher and being able to train and shape the new additions to the department is an awesome pat on the back."

It is okay to brag a little bit when answering this question. Show that you are proud of yourself and your career accomplishments by talking about what you feel has been your biggest success to this point. Walk your interviewer through the hard work you had to put in to achieve this accomplishment, and reiterate that you are ready to bring this same sense of success to work at Allergan.
