Hopper interview questions

Did several tasks and had 2 Skype interviews. Tasks made me excited to think about working there but I did not receive any feedback after rejection, even after asking which was disappointing given the amount of time I put in.

I just participated in online tech session. Were given coding assessment in a website. The problem is not hard, its about nest node (a parent node has a list of children, each child node has a list of children node, etc). However, I think there is lack of clear explanation of the code structure, which is confusing, and I took 20 mins just to figure out how the code is structure.
