Yeah, In the first interview you are asked general questions about your current and past work history, you are supposed to just sell yourself and make a lasting impression enough for them to want to see more of you after the group work. They also ask you about the job and what you think is involved and what you know about
VB. It goes by pretty fast, and all of the recruitment team are great! You will not feel nervous longer than the first few minutes.
In the longer one, you are talking in depth about your customer service experience and situations you have handled well, situations that were stressful etc.. so have plenty of examples handy, don't prepare so much for the actual question, but 'know' the scenario you experienced.
