If I were you, i would google "white rabbit scam glassdoor" to see real reviews that aren't written by their staff! It is a complete scam, the do the whole process so quickly that you do not have time to process the actual job role and research thoroughly. Arrived at the "assessment centre" which was actually door to door sales whilst they were also training a new joiner, ate a co-op meal deal in a random guys car and didn't get back to the office until 10pm where I had a final interview with Nathan Simmons and I must be honest he is a good sales man, he was able to sell me the false dream of being successful like "he is". I asked him to run me through the day to day tasks for a graduate management trainee and he failed to answer my question by completely avoiding it and talking about something else.
Don't get wrapped up in the false dream they are selling! All you will be doing is door to door sales for gas and electric.
