Tip 1 : I was informed about the interview only 3 days prior to it. So, if you find yourself in a position like me, one thing I would mention is to NEVER LEARN ANY NEW TOPICS if you have less than 2 days. Brush up on the topics you already know.
Tip 2 : Practise Time and space Complexities well. Know your basics and practice as many questions as possible on LeetCode.
Tip 3 : Refer to previously asked questions in the interview of the company. Read about the interview process for the role you're applying for. Learn about the role and the company as well.
Tip 4: If you're new to giving interviews, practice mock interviews with your friends or family.
