I was given 3 question in the online assessment on hackerEarth from leetcode they were Easy, medium and hard .Easy one was on dictionary , Medium was based on dfs and hard was on priority queue .

Interview starts with completing a online test that has 3 questions 2 of medium, and one hard. I solved all three so I had the interview, the process is very smooth, they ask about your experience in problem setting and having a good profile on codechef is must.
