OneMain Financial Credit Risk Analyst II interview questions

I met with the HR manager first who who basically asked me questions about my history with the company. I was then introduced to the hiring manager who was very casual and easy going person. He started the interview by asking about my past jobs with the company and how I would fix a certain issue that his department was having at that time. There situation had to do with a previous job that I did for the company many years ago. I, unfortunately, was not prepared for the question aked and could clearly see that I was not going to get the job. I felt that I was prepared for the interview, but I was more prepared for behavioral type of questions. It had been awhile since I had been on an interview and I realize that I cannot just focus on one type of interview, I have to prepare for them all.
