I worked at Booker Group full-time (Less than a year)
Great management, co-workers make the days pass. Do your job, get paid. It's that easy. Free breakfast on Mondays, so that's cool.
Customers can be awfully mean at times. Just need to let it roll off your shoulders and move on.
Advice to Management
Just do what you do.
The process took 1+ week. I interviewed at Booker Group (London, England (UK)).
I was taken into a room to fill out basically another application form and after that I was taken into another room where 2 managers interviewed me. They asked 3 questions which were easy to prepare for. They said they will be in touch but it's been 3 days and I have currently heard nothing.
