I did the non-Potential test in the Milan office some years ago (2011) and got confirmation that last year (2017) was still the same; the test consisted of two parts:
- Numerical test. Very similar to the SHL numerical part. Paper-based, each question had 5 or 10 possible answers. Questions were not hard, but time was really short.
- Resources: You can train online on SHL type cases with a strict time constraint. You can find an example of a SHL numerical test at the following link:
- Logic test based on traffic lights colours. Technically speaking, the test is called Fault diagnosis. In the test, two or more traffic lights are connected by codes; each code changes a colour of the traffic light; one or more of the codes are broken and you have to understand which are the broken ones. It was a bit complex to understand the logic initially, but once understood it the test was not particular difficult.
