Tip 1 : Topics from Coding Ninjas of Course Competitive Programming. Practice atleast one question everyday from sites like Leetcode,Interviewbit and also took part in Codeforces Contest.
Tip 2 : Though Data Structure is the base for any tech interview, one must know some other subjects as well like Operating System, Networking, and Database Management System for which I took help from Coding Ninja’s notes and from GeeksforGeeks. Along with this stuff, read about puzzles on GeeksForGeeks. Overall, Coding Ninjas & Geeks For Geeks have a big hand in making me crack this interview.
Tip 1 : Keep your resume up to date and mention 2-3 good level projects which will give a good impression to the interviewer .
Tip 2 : Don't put false things on the resume.
