Tip 1 : Practice Questions as much as you can
Tip 2 : Do at least 2 projects
Tip 3 : Do practice a lot of questions on linked list and stacks as these are two most important data structures asked in the interview.
Tip 4 : Also, try to implement it yourself without seeing the solution.
Tip 5 : Also prepare for Computer Science subjects like Operating System, Database Management System, Computer Networks, etc. I prepared them through Coding Ninjas notes which were simpler and easy to understand.
