Santander Customer Service Advisor interview questions

I applied online through the Santander UK website, I was then invited to a phone interview which I'm going to be reviewing here (I will then write another review about the assessment day): First of all, the interviewer called me about several hours after the interview was scheduled and did not apologise about this. Then I started to answer questions...and at the end I was informed about what will happen if I am successful at this stage, which I was.

Apply online by sending a cv then if successful they invite you to do an online assessment which includes competency based questions, maths mainly percentages, and database work. If successful they send you an email to book a telephone interview which again ask you questions about your previous work. Tell me a time..
