When you are applying for an entry level position a typical job interview question is "What major problems have you encountered at work and how did you deal with them?"
Here are sample interview answers which you can edit to fit your personal experiences and background:
I feel that the best way to deal with any challenges is to meet them head on. When I found that one of my colleagues was saying things that weren't true behind my back, I went to him and talked it through. It turned out that he had misunderstood what I had said, and I was able to set the record straight with him, and my supervisor.
Once I found a major flaw in the work of one of the most senior members of the department, which could have been very costly to the company if it had been overlooked. I went directly to him, and called it to his attention so he could fix it before it affected the final outcome.
One of the major problems I have found in this profession has been a lack of proper funding for the programs we are trying to implement. I think that I have a lot of creative ideas to help overcome some of the budget limitations inherent in this type of work.
