I did the test as well. Not a big deal to be honest. First pen & paper test to check if you can think in a logical way. It took around 20min. After that some questions with the computer. In total maybe 250 questions. Sounds like a lot, but you just have to answer what first gets into your mind. There are only 15 questions where there is a right/wrong answer. All the others are there to "open" your attitude and personality to the shrink.
Test was scheduled in the morning hours. Depending on how fast you are, you receive your feedback right after the test. Otherwise you need to wait untill afternoon. Depening on your accomodation, you can go back to the hotel.
The feedback was quite cool. I did this last time for LH and they just said, you´re good enough or you´re not. I´m not a shrink fan and went there very reserved. Sometimes I thought, how the hell did he know
... but it was quite entertaining.
The shrink sends his impression to the interviewers, it´s not a recommendation.
Just be yourself and mark the first answer which gets into your mind, thats it.
