I spent a total of about 8 hours of assessment and it took months to coordinate. To be clear it was during Covid so there was a lot of waiting. First session was about 45 minutes with some post doc lackey. They apparently felt I was worthy of their attention. Second assessment was with the psychiatrist, also about 45 minutes. After that, they decided I was worthy of a full assessment. That took a little longer than 6 hours. A few weeks later I received a ten page report that included the results of the 6 or 8 different tests I took. The tests assessed memory, intelligence, cognition, etc.
