Pros
There are some really good managers in the business, with some exceptionally motivated sales people. Broaden's your horizons - you get to meet new people from different countries. Money to be earned in the long run when you become a consultant.
Cons
Don't listen to anyone that tells you there will be a £40K salary at the end of the 4 weeks training. They lie to you and mislead you with this, it's a way of getting you in. It's supposedly after you become a consultant which takes at least a year, even after that they don't want you to take it. They tell you this to get through the door, you will be on a £1200 a month retainer and everything will be commission only. Which takes about 6 months to get a bonus, so most people are playing catch up. They fire a lot of people during the training, for the most pathetic reasons. You have to pay for your own working visa with your commission. Very unprofessional with clients and employees. Use of bad language in training academy. Long hours, no work life balance. Medical insurance is very poor and basic, you will have to pay for it yourself for a decent one. Data mining and cold calling is all you will be doing.
