Hi, Yes there is a group interviews too. You all sit around a table and discuss a senario together. They are just looking for people who contribute to the conversation, give eye contact to the rest of the group, try and include others in the conversation and basically act like a team player ie. contribute but also value the opinions of others.
The salary is a basic of £11,000 plus 2.40 per hour plus bonus payments for performance. They were quoting in the Mail that this would amount to £18,000 per year but I couldn't tell you if that is realistic or not because I am current crew and I don't get paid that way.
Hope that helps.
