Interviewed Sep 2009 (took 3 months)

The Interview process is slow. Wrote an online questionnaire. This is to know if you have the personality they want. I then had a telephone Interview two days after wards. I was asked very simple maths questions. 3 in all. A calculator is allowed. All the questions asked were competency based, where you have to give scenerios of what happened and what role you played. I was told immediately that I passed.
I had a 1 to 1 interview 5 weeks after. Interview questions were same as telephone interview questions. Its ok to use the same answer. I was called the next day and told I Passed but that the vacancy was filled. I was invited for the final interview 7 months thereafter. Same kind of questions. I passed and got the offer the next day.
Advice is that use different scenerios when aswering the questions but all should be related on effective and quality customer service.

Good luck.
