Online assessment:

Two problems to solve( 90 min) + Behavioral (15min):

• The second problem was a hard one (didn't find it on leetcode), I managed to find a working DFS solution within 20-30 minutes (all tests passed) ! Edit: I found it : https://leetcode.com/problems/unique-paths-iii/

• You have to explain which data structure you used and provide Big-O runtime complexity
