## Introduction

A significant portion of coding interviews in machine learning and data science focuses on data structures and algorithms. In this article, I detail the 6-week process I followed to prepare for such interviews.

## Move Away from Traditional Methods

The first step should be to move away from traditional methods of learning data structures and algorithms. This approach requires focusing more on practice than theory.

## Practice-First Learning

Starting to solve problems before learning the topics makes the learning process more effective. This method reinforces theoretical knowledge with practice.

## Daily Routine

Working on two problems every morning for 30-60 minutes over 6 weeks ensures continuous learning. This routine enhances problem-solving skills.

## Understanding Solutions

When solving problems, it's important to understand the model behind the solution, not just the answer. This leads to more effective long-term learning.

## Focus Areas

Focusing on topics frequently asked in machine learning interviews is crucial. These topics include arrays, hash tables, and trees.

## Skipping Advanced Topics

Instead of learning advanced topics like dynamic programming and bit manipulation, focusing on more frequently asked basic topics makes better use of time.

## Conclusion

This approach transformed my understanding of data structures and algorithms and significantly increased my success rate in coding interviews.
