Assessment centre Python challenge was ridiculously easy. The interviewer I had seemed to be very clueless on anything programming related. He asked me a question that he likely thought I wouldn't get, once I got it he quickly asked a different question that specific about Java that if you'd never done it, you'd never ever know.

Assessment day was well organised, gave a good overview of the job and what is to be expected. They made the activities fun and engaging and the 1-to-1 interviews were short as it was revolved around an individual task however opportunities were provided for questions throughout the day with various employees.
