๐Ÿ‘จ๐Ÿปโ€๐Ÿ’ป One of the most popular GitHub repositories for "learning and using algorithms in Python" is The Algorithms - Python repo with 196K stars.

โœ๏ธ It has a lot of organized and categorized code that you can use to find, read, and run different algorithms. Everything you can think of is here; from simple algorithms like sorting to advanced algorithms for machine learning, artificial intelligence, neural networks, and more.

โœ… Why should we use it?

๐Ÿ”ข For learning: If you're looking to learn algorithms in action, this is great.

๐Ÿ”ข For practice: You can take the codes, run them, and modify them to better understand.

๐Ÿ”ข For projects : You can even use the codes here in real-life or academic projects.

๐Ÿ”ข For interviews: If you're preparing for data science interviews, this is full of practical algorithms.

๐Ÿ“„ "Pandas Introduction to Advanced" booklet

๐Ÿ‘จ๐Ÿปโ€๐Ÿ’ป You can't attend a #datascience interview and not be asked about Pandas! But you don't have to memorize all its methods and functions! With this booklet, you'll learn everything you need.

โœ”๏ธ One of the most useful and interesting combinations is using #Pandas with #AWS Lambda, which can be very useful in real projects.

๐Ÿ”— Machine Learning from Scratch by Danny Friedman

This book is for readers looking to learn new #machinelearning algorithms or understand algorithms at a deeper level. Specifically, it is intended for readers interested in seeing machine learning algorithms derived from start to finish. Seeing these derivations might help a reader previously unfamiliar with common algorithms understand how they work intuitively. Or, seeing these derivations might help a reader experienced in modeling understand how different #algorithms create the models they do and the advantages and disadvantages of each one.

This book will be most helpful for those with practice in basic modeling. It does not review best practicesโ€”such as feature engineering or balancing response variablesโ€”or discuss in depth when certain models are more appropriate than others. Instead, it focuses on the elements of those models.

๐Ÿ’ฏ Top 100+ Google Data Science Interview Questions

๐ŸŒŸ Essential Prep Guide for Aspiring Candidates

Google is known for its rigorous data science interview process, which typically follows a hybrid format. Candidates are expected to demonstrate strong programming skills, solid knowledge in statistics and machine learning, and a keen ability to approach problems from a product-oriented perspective.

To succeed, one must be proficient in several critical areas: statistics and probability, SQL and Python programming, product sense, and case study-based analytics.

This curated list features over 100 of the most commonly asked and important questions in Google data science interviews. It serves as a comprehensive resource to help candidates prepare effectively and confidently for the challenge ahead.

๐Ÿผ "Comparison Between SQL and pandas" โ€“ A Handy Reference Guide

โšก๏ธ As a data scientist, I often found myself switching back and forth between SQL and pandas during technical interviews. I was confident answering questions in SQL but sometimes struggled to translate the same logic into pandas โ€“ and vice versa.

๐Ÿ”ธ To bridge this gap, I created a concise booklet in the form of a comparison table. It maps SQL queries directly to their equivalent pandas implementations, making it easy to understand and switch between both tools.

โšก This reference guide has become an essential part of my interview prep. Before any interview, I quickly review it to ensure Iโ€™m ready to tackle data manipulation tasks using either SQL or pandas, depending on whatโ€™s required.

๐Ÿ“• Whether you're preparing for interviews or just want to solidify your understanding of both tools, this comparison guide is a great way to stay sharp and efficient.

๐Ÿ”ฅ How to become a data scientist in 2025?


1๏ธโƒฃ First of all, strengthen your foundation (math and statistics) .

โœ๏ธ If you don't know math, you'll run into trouble wherever you go. Every model you build, every analysis you do, there's a world of math behind it. You need to know these things well:

โœ… Linear Algebra: Link

โœ… Calculus: Link

โœ… Statistics and Probability: Link

โž–โž–โž–โž–โž–โž–

โœ๏ธ Everything you've learned so far is worthless without a real project!

โ—€๏ธ Participate in Kaggle and work with real data.

โ—€๏ธ Do a project from scratch (from data collection to model deployment)

โ—€๏ธ Put your code on GitHub.

โœ… Open Source Data Science Projects: Link

โž–โž–โž–โž–โž–โž–

7๏ธโƒฃ It's time to learn MLOps and model deployment!

โœ๏ธ Many people just build models but don't know how to deploy them. But companies want someone who can put the model into action!

โ—€๏ธ Machine learning operationalization (monitoring, updating models)

โ—€๏ธ Model deployment tools: Flask, FastAPI, Docker

โœ… Stanford University MLOps Course: Link

โž–โž–โž–โž–โž–โž–
