Interviewed at headquarters in May. Was really overcrowded was seen over 2 hours late to due to masses of people. Which was appalling but the staff were helpful and regretful of the timing, but they kept us informed and updated so I stuck through. During this time they Scanned my passport and proof of address. Eventually Was sent with a group to do a simple written maths exam with calculator. Then waited to be interviewed 1 on 1 with management. They checked my cv and started the interview. In 2 days I got a call back confirming I got the job and 2 weeks later was set up for a 2 day induction.
