After the first stage, where I fill in my details and other personal information I got a link for online assessment. It contains 22 questions. Approximately time needed 30 min. That's what they said. It took me much longer to finished it. The questions are relatively long and there are 4 answers, as well relatively long. You have to pick up one as most efficient and least efficient. You just need to read carefully all the information and to choose the answers according to your point of view. The number and type of assessments will depend on the role for which you are applying. You can take the assessments at any time within a fixed number of days, as specified in the email.
