I applied online. The process took 3 months. I interviewed at FirstGroup (Birmingham, England) in Feb 2016
Interview
After the initial online application, you are required to complete online tests. One of the easiest I have completed out of any graduate application. Next you have to do a video interview before you are invited to attend the assessment centre. The assessment centre started the evening before - FirstGroup pay for your dinner and stay as well as giving you drink vouchers so you can socialise with staff and ask any questions you wish. The next morning is the start of the assessment centre which involves group tasks, individual tasks as well as an interview.
