Process
I got killed too. I performed so poorly, scoring 27%. I ended up with a 100 on the real one, though, so don't lose hope.
After looking at the problems, you should make sure you brush up on DP (dynamic programming) and graphs. From what I remember, at least two of the three had DP or graphs.
Neetcode has 10 LeetCode questions for both, I guess. Check HackerRank's questions too.
Try some hard problems and learn how to manipulate adjacencies, etc.
Wishing you luck! (Again, I was so stressed until I took it last minute. Keep practicing and getting better.)
