Utterberry interview questions

An initial 2 hour assessment. Then asked later asked to come back for an interview after a 3 week wait. Which was organised for 3 weeks in the future. Then the day before, I was asked instead of coming in at 1.40 to come in at 1. I spent the whole afternoon doing some pretty pointless group activities, waiting for an interview. After waiting for 4 hours, I never did receive an interview and only 3 out of the 6 people there did. We were told that they would organise and interview on teams with us, which they never did. I attempted to contact them by email to organise the interview which they didn’t respond to. So overall 7 hours wasted, and not even the courtesy to tell me that they would not be moving forward with me anymore or any feedback.
