International Rescue Committee interview questions

I applied through the website. Two weeks later, they called for a phone interview for someone from HR. The person replied quickly to my emails, and it was quite easy to schedule an appointment. She told me a little more about the position and ask me if I was still interested. I was a couple of days ago, so I haven't heard back, but they explained the process and were open to questions.

Explain a situation how you dealt with a difficult situation? What strategies did you use? Did you involve anyone? What are your weaknesses? What are your strengths? Tel me something I don’t know about you?
