Dose of Fundamentals (Java)

Are you having trouble passing technical coding interviews consistently? Coding interviews are no joke, and I want to help you master passing all your interviews with flying colors.

This book is part 1 of the series on acing your coding interviews. This book will cover all the elementary topics for data structures and algorithms (big O, hashmaps, stacks, queues, and linked lists). I also have covered famous coding problems that I have seen and how to approach them in a detailed manner. There are also diagrams to visually understand what is going on.


This is a book written by me. I have worked at big tech companies, such as Amazon and Twitter. Currently, at Twitter, I am on a backend infrastructure team, focusing on essential pubsub services, such as Kafka.

I have numerous experiences prepping people for coding interviews. I have helped over 75+ clients in preparing them for job interviews. I have gotten clients jobs at top companies, such as Amazon, Square, Facebook, and DoorDash. I have racked up almost 500 hours tutoring people on data structures and algorithms. As a result, I ensure that my client knows how to recognize which technique to use during a coding interview as well as knows how to execute that technique.
