Firstly: You had to write a personal statement, something to describe yourself
Test 1: Involved ticking (agreeing) with a list of statements from two perspectives. The first perspective was how you see yourself. The second perspective was how (you think) others see you
Test 2: Involved rotating the letter R many times in a fixed time period. I was given a grid of about 100 R's all at different angles and had to count the number of clock wise rotations for it to be normal.
The end-result was basically a bunch of weightings that gave personality traits. Followed by a really well written auto-generated description of that individuals traits.
Typically when people had the chance to read their results, they'd say "ooh, actually I agree". But of all the things it said - there was a hell-of-a-lot that it didn't say.
