3 stage process. Really relaxed, straightforward and easy. 1st stage was a phone call conversation to measure customer relation skills. You follow a worded script, of which you have to follow but can change the order of questions you ask. 2nd stage was a numerical and reading comprehension paper exam. They are very basic arithmetic and basic common language questions. No need for a calculator. 3rd stage is a face-to-face interview with one of the heads of the department. They ask you questions with regards to your CV and what you can contribute to the role and then basic irrelevant questions, such as if you have booked any holidays and if you would be looking for something else, even if you get this job (i answered I would still be looking for other jobs despite I get this one or not, and still got hired on the spot). Overall, really easy. No need to practise, study or prepare anything. Since it is an entry level position, training is provided and all you are really required is some sort of customer relation experience, anything that says you can handle people and a telephone.
