Pretty straight forward. Write a CV, cover letter and you're asked to fill in an application form. Then you're invited to a video interview, and if you're successful then you go to an assessment centre

It was very messy, I did the online test, application form, and the video interview. They then informed me that I was unsuccessful but then emailed back saying I was successful and passed onto the next stage of the interviews and it was an error and then ignored my follow up emails.
