Omnicare interview questions

I applied for a position online and 4 days later they contacted me for a phone interview, the phone interview went well so they contacted me back for a job interview. The job interview I was told would consist of two exams and I would be sent the information I needed in order to study for it. My interview was set up for 4 days later and I have to study the top 200 drugs and had to know the brand to generic and their infractions, as well as a list of sig codes, and conversions. I went and took the two exams and I did very well therefore I went on to the interview. I interviewed with someone from Hr it went extremely well and then on to someone from the department she gave me information about the position and asked me several questions. Soon after that I sat down with a technician and was shown what I could be doing if hired. The interview went extremely well the personalities were great and I really liked the environment. I got a call two days later for an offer and accepted the position. I'm coming from retail pharmacy making $15.00 an hour and they offered more then that. I'm most looking forward to actually having lunch, being in an office like setting, and making more money. Also they have lots of overtime which is very appealing to a mother who has a family to support. This could be very beneficial for birthdays and Christmas.
