First and online questionnaire, then a 20min phone interview asking about previous experience and to give an example of offering exceptional customer service. Then a assessment which involves a presentation, group discussion on vodafone (how big it is, what they offer and what they are developing), then a mock call with a customer not pleased with the customer service and want to leave. Then finally a dragons den type set up where you need to design a new and inventive app. Process is quite relaxed and they make an effort to avoid it being stressful.
