Preparation

Duration:
4 Months
Topics:
Java, Data Structures and Algorithms, System and Database Design, OOPS
Preparation Tip

Tip 1 : If you are a newbie to programming, I will strongly recommend to practice LC/GFG/CodingNinjas Easy questions for clearing the basics. Once you gain confidence, you can move on to tackle medium and hard questions.
Tip 2 : Most companies require individuals to know System Design well. For somebody with 1-3 years of experience, database designing (identifying entities, their relationships and constraints), OOP concepts and API designing for Low Level Design is a must. I would recommend the "System Design Interview by Alex Xu" book for HLD preparation.

Tip 1 : Have an updated and properly formatted resume
Tip 2 : The resume tells your story so you ought to know and be able to explain whatever you've written. 
Tip 3 : Do not include technologies/skills that you've not worked on at all. It can blow the interview if the interviewer questions you about it.
