Tip 1 : Focus on data structures and algorithms part more.
Tip 2 : Try to do as much deep study of logic as you can’t memorize each question so the only thing you will remember is the logic part which you have applied.
Tip 3 : Also, try to do lot of practice for Data Structures and Algorithms related problems. I personally used Codezen and Geeks For Geeks. You may refer to any portal but I suggest you to use Codezen of Coding Ninjas as you can get a variety of interview problems there.
Tip 4 : DO projects properly

Tip 1 : Write what you know and know what you write
Tip 2 : it’s better not to exaggerate and getting into your own trap.
Tip 3 : To be honest, the problem-solving ability is the only thing that most companies care about. So you can manipulate your resume according to that.
Tip 4 : Mention your competitive programming handles in your resume and also other coding ranks or achievements which you have achieved.
