I was a Customer Service Advisor so I'll write about what I know.
For hints as to how to conduct yourself or things to say, pay attention to the job description, check out their homepage, to see what's hot, and their CEO's blog.
Wear smart professional but no need to overdo it as they're pretty tolerant about looks in the work place: there's no dress code as such, just exercise your common sense (nothing offensive or unprofessional, logically). Performance matters more.
Show an open mind and willingness to learn, and that you're ready to handle what's thrown at you ("yes, I can do that" or "that's not a problem" are always winners).
If you pass this stage, you and other hopefuls will go on to Assessment day when, among other activities, you'll go through some written tests to assess your basic maths, language and other necessary skills. For the maths test, read the sheaf of printouts they gave you previously, it shows all you need to know. The test is short, nothing complex; don't worry if you can't finish it all in time, what matters is what you write in it, and HOW (be accurate, concise and to the point: given the volume of calls if you have to deal with daily, they need people who can think on their feet and juggle quite a few balls at the same time).
You'll know if you were successful or not within the half hour.Answered 9 January 2019
As a customer service advisor, are there overtime opportunities? And if so at what rate?Asked 13 December 2017
There's not much overtime. But there's always extra work at the emergency centre in Hilsea, they work 24/7 and pay well. If you go for this and you're on call, ideally you should not a car as they can call you at 11 at night for example. But due to the fact that you made yourself available and were on call (you stayed indoors or nearby when you could have been doing something else), you'll get paid whether they need you to come to work or not. Obviously it's not the same pay if you work or not, but the rates are pretty much anyway. If you're ok with crazy shifts, you should grab this one.Answered 9 January 2019
