@Hitoyou Sorry to hear that it was not a good experience.
The logistics were a bit messy - we were told to come back by a certain hour but by then our DD had not yet had her interview and the same for quite a few others. But other kids in her same time slot had already finished and gone home. As there was also a certain overlap with the DC and families in the following time slot there was quite a crowd with staff trying to keep up.
I do not think that it was DD's finest hour either - apparently there was some initial confusion over which group she was supposed to be in, and I think that distracted her. Between that and the fact that the numbers are rather mad (over 600 kids) I am not holding my breath either.
