It wasn't really difficult. If you know the cookie cutter questions, you can easily walk through this interview. I have added a question when I interview people: What is your passion when it comes to business analysis? Why do you want to be one?
Understanding a part of the business well enough to come up with effective solutions that require minimal effort and then getting the required buy-in from other people in the organization. The political dynamics are an important reason for doing the job.
The economy doesn't support small businesses right now and I need to return to corporate in order to make a living. Because I like being the support that help the ones around me succeed, I am looking for an Executive Assistant position. I like knowing that other people can pay attention to making money while I keep the world around them running smoothly.
I answered that my biggest strength and weakness was actually the same thing - my emotions. I answered that I was going to help the company grow by working my way up in to human resources and helping find great people to work on an already awesome team. Two and a half years later, I have done so and couldn't imagine working anywhere else. I love what I do every day and come to work singing. My fellow team mates do the same thing.
Remain calm and try to gauge the situation, always pointing out you're willing to help but not to the point where you jeopardize your other tasks. If they prove to be too difficult, then seek advice from higher.
