First step was a test, the usual numerical and situational judgement tests.
One you pass this, there is a video interview, it's a mixture of video interview questions and typed up responses (you get a question and have a fixed time to type out your answer)
Third Step is an assessment centre and I had an excel assessment along with this.
Final step was an informal chat with the team to essentially see if you would fit with the team, but also a final opportunity for you to ask your own questions to see if the job itself would fit you.
