AVEVA Technical Support Graduate interview questions

Applied online. Soon I received email back asking me to complete a test. Then had a 15-minute online call asking general questions about myself and interest in role. Then had an assessment day which was approx 5 hours. Included 4 exercises. Group presentation, 1 on 1 presentation, written exercise & 1 on 1 interview (not very professional). Only word I heard from them following the day was them asking for feedback on the day, but they refuse to give you any even if asked. Bit of a waste of time really, it doesn't take long to send a generic rejection email.
