I attended the video interview 10 days after submitting the application. It was a long interview with competency questions and a short case study. I only got one chance to record the answer.
I applied through an employee referral. The process took 3 months. I interviewed at Accenture (London, England) in Dec 2017
Interview
Online testing (maths, logic, reasoning) followed by video interview. After the video interview I was offered an assessment centre and one to one interview (not yet completed) at their offices in London.
