Tip

Tip 1 : Find a good course, and first clear all your fundamentals and implementation of every data structure. You should be thorough with their time as well as space complexities.
Tip 2 : Upon clearing the fundamentals, select a platform where you have a large no of questions, also whose test cases are good. eg. LeetCode, InterviewBit or Codezen. Go and complete 300-400 questions.
Tip 3 : Also whenever you're not able to solve the problem, check out the editorial and then re-attempt it again. Also, check the discussion if there is some good solution to the same problem.
Tip 4 : For OOPS, DS and programming, I recommend Codezen, Leetcode, InterviewBit and GeeksforGeeks.
Tip 5 : For OS, DBMS and Computer Network, I recommend GateSmasher, Knowledge Gate and TutorialsPoint.
