You will need to submit your CV and Covering letter (basic information as well)
Then in one or two weeks, they will come back to you and send you an email notifying you to take the first online test: 6min numerical test and 6min data analysis test.
(I forgot how long are they, but it is pretty quick and didn't take you 30min or longer. You need to work very fast and read carefully at the same time.
After the first OT, you will then receive the second OT: Behaviour test. Just to be honest and be yourself. They will check if you are honest by asking some similar questions multiple time.
After one week, you will receive a video interview, which is required to complete with written and video response. I am currently at this stage and if I am successful, I will update my experience with you.
Note: I am applying for the Summer Internship (Talent division) in the UK.
