A technical test at home of litcode questions and then 2 interviews with team members, they were very nice throughout the whole process and the process was good even though I didn't pass

I got a HackerRank home assignment with 2 leetcode questions, one was easy the other was medium-hard. It was a sliding windows, and a buy n products with the minimum coins at start. There were 2 arrays, one of the WC cost of the products and one with the expected cost.
