Before proceeding to the first interview, I had to complete personality and capacity tests. The recruiter sent me the links and I had 5 working days to complete them both. The personality test was straight forward and the most important thing was to be honest and as a result consistent. Questions repeat themselves in different ways.
Now, before you complete the capacity test they provide you with 4 questions to practice. The problem with that is that the answers for these example questions are pretty easy and the difficulty is very low. When you start the test you realize that the questions are much more difficult and time is running...so, the example questions are misleading, since you expect similar/slightly higher level of questions.
