I applied for the customer service representative position, and I was contacted (phone) to do an interview within a few days. It was only one interview with two individuals back in the spring of this year. I didn't do much preparation because it was an entry level position. I just tried to brush up on my behavioural questions. The interview was relaxed and seemed a tad informal actually. It was mostly behavioural and "getting-to-know-you" type questions (about 12 or 13 or so). A couple of knowledge-based questions. I got the offer the next day. The workplace is very structured and rigid. Not a lot of room for flexibility but great people working there. My advice? Don't sweat it. Just know what you did in your previous job(s) or school experience and somehow tie it in to the customer service position.
