Wise Senior Backend Java Engineer interview questions

It was an 1 hour coding interview on HackerRack with 2 interviewers (Indian). When I started to code, they asked question regarding to the implementation before or at coding phase. They try to help, but they don't even give time to think the overall solution. The datastructure was a little bit more than I first thought. So the help was not a help for me, but a barrier mostly to be able to think of the whole implementation. The time was not enought in these circimstances.
