The Technical Interview Preparation
The Grind 75 of LeetCode

For the questions I could not solve, I watched NeetCode Blind 75 YouTube videos

The Tech Interview Handbook
Skimmed through the data structures and algorithms cheatsheet. I learned all of these from class since I am a computer science major, so I only needed to skim through them.
CodeSignal
Going back I would start with CodeSignal instead of the Grind 75 list because the questions are easier. After I was confident, I did a few CodeSignal Tests. I often did poorly on the CodeSignal tests usually getting either 0-2 questions out of 4 correct, but I kept doing them twice a week in the last month and it improved my problem-solving ability.

To learn coding techniques I mainly googled them and learned them from Programiz, GeeksForGeeks and YouTube. I also studied a few coding interview cheat sheets and articles.
Time Complexity
I learned about how to analyze time complexity from this video by Ben Awad.

The Big O Cheat Sheet is the most popular resource on Big O notation, but I personally found the python wiki more useful.
