Course Description

  • Want to master popular problem-solving techniques, data structures, and algorithms that interviewers love? Dive right in!

  • Crave step-by-step explanations for the industry's hottest interview questions? We've got you covered.

  • Looking to up your game in competitive programming? Buckle up for a thrilling journey!


Welcome to the course!

In this course, you'll have a detailed, step by step explanation of hand-picked LeetCode questions where you'll learn about the most popular techniques and problems used in the coding interview, This is the course I wish I had when I was doing my interviews. and it comes with a 30-day money-back guarantee


What is LeetCode?

LeetCode is essentially a huge repository of real interview questions asked by the most popular tech companies ( Google, Amazon, Facebook, Microsoft, and more ).

The problem with LeetCode is also its advantage, IT'S HUGE, so huge in fact that interviewers from the most popular companies often directly ask questions they find on LeetCode, So it's hard to navigate through the huge amount of problems to find those that really matter, this is what this course is for.

I spent countless hours on LeetCode and I'm telling you that you don't have to do the same and still be able to get a job at a major tech company.

Course overview :

In this course, I compiled the most important and the most popular interview questions asked by these major companies and I explain them, in a true STEP BY STEP fashion to help you understand exactly how to solve these types of questions.

The problems are handpicked to ensure complete coverage of the most popular techniques, data structures, and algorithms used in interviews so you can generalize the patterns you learn here on other problems.


Each problem gets multiple videos :

  • Explanation and intuition video(s): we do a detailed explanation of the problems and its solution, this video will be longer because we will do a step by step explanation for the problems.

  • Coding video(s): where we code the solution discussed in the explanation video together.

  • Walkthrough video(s): where we go over each line of code and see what it does


We will use basic python for this course to code our solutions, previous knowledge in python is preferred but NOT required for the coding part of the course.


The problems are categorised for easier navigation and will be regularly updated with more popular and interesting problems.


Some of the stuff this course will cover are :


  • Arrays and Strings interview questions.


  • Searching interview questions and algorithms.


  • Dynamic Programming interview questions.


  • Backtracking interview questions (  With step by step visualisation ).


  • Trees and Graphs interview questions and algorithms.


  • Data structures Like Stacks, Queues, Maps, Linked Lists, and more.


In other words, this course is your one-stop-shop for your dream job.

Instructor Details

Interview Temple

I am a professional software engineer with a passion for teaching and a strong believer in lifelong learning.

I am not one of those guys who started programming at the age of 3 and stuff like that, I started programming in my first year of college, I struggled, built stuff, failed many times and finally through countless hours of hard work I managed to become a professional software engineer in a very respectable company that you probably heard of.

I am here to teach you all that I know about software engineering, web development, data structures and algorithms

I hope to save you tons of hours skimming through tens of resources online as I did, and I sincerely hope that I could benefit you as much as possible

Bit is incredible. Gearing up for a big interview and this course taught me so much. I hope he comes out with another course and 50 new problems. His explanations and walkthroughs are amazing. His break down of all the data structures is invaluable.

By Antonio Viggiano on 1/31/2023

Good content and good presentation of algorithms and data structure concepts. I would recommend this course for someone who might have an interview and doesn't have a lot of time to practice hundreds of LeetCode exercises. The only thing that's missing is some polishing on the presentation slides: they do not always follow the same standards. Some are in blue, others in black, the typography changes, etc.

By Petar Kerefeyski on 1/21/2023

TL;DR - good for absolute beginners, not recommended for more advanced. All data structures are explained decently. Each problem has a walkthrough, but with the medium/harder problems, the author jumps straight to the optimal solution - the videos are lacking the "intuition" for each solution. The easy problems are explained pretty well, but medium and harder problems often lack Space-Time complexity analysis and some of the walkthroughs are ended at the thickest parts. It leaves the impression that the author just found the optimal solution on the internet, explained it in a few slides, and skipped whatever he was unsure of. That may totally not be the case.

By Bernardita Stitic on 3/8/2022

I’ve learnt a lot during this course, I think the explanations are very clear. I especially liked the walkthroughs which are guided steps of the solutions , this further clarified hard problems. And also, the instructor is very patient with our questions, I really appreciate having the chance of being able to make questions and get help. Thank you so much for all your work and dedication, Bit! :D

By Anil Kumar Behera on 8/15/2021

Voice quality is not that great and is not consistent throughout the course. Explanations are most of time good and easy to follow except for few problems where it is either very lengthy and is difficult to follow. Also would be good to have some improvements on how to think about the solution for a specific problem than simply specifying the solution.

By Nan Kat on 6/14/2021

The Instructor is really great! Bit answers questions very fast and in a comprehensive way. The selection of exercises is great too. It really trains your brain and will definitely bring you forward in your SW engineering skills.

By Claudio Mello on 4/18/2021

Great course. The instructor explains the problem and the solution in detail. Then implements the solution and test it in Leetcode and in the Visual Source Code. There are some minor errors in the text, but it is not a problem at all. Thank you.

By Anonymized User on 3/18/2021

Very clear explanation, the walkthrough always you to think, analyze and figure how and why everything would work, I found that extremely helpful in backtracking section. The instructor is clear and engaging and the code videos are very easy to follow. Great work on this course, I highly recommend it if you are willing to build your skills in problem solving.

By Gautam Pai on 12/30/2020

I enjoyed this course throughout. Thanks for arranging this content. It was a wonderful course. I had little trouble initially in adjusting with the course material but practice and persistence helped me to keep up with the course and also the turnaround time of the instructor is excellent. The one thing that could be improved is the audio (I had headphones always on) and also have some sibling problems to a problem solved that we could apply the same concept and exercise our brain. Anyway thanks for keeping this wonderful content. Highly satisfied

By Alexandra Duboy on 11/14/2020

it was hard to follow

By Kavya p on 11/1/2020

Amazing course content with a crisp explanation.Every problem has 2 videos one with a pseudocode explanation other is the actual code. The course is a combination of 50 leetcode problems along with basic data structure explanation. The tutor is really quick in responding to student queries. This course is totally worth it . Must buy if you are serious about your interview preparation.

By Gauthier Delvaulx on 11/1/2020

It is often too difficult to understand. I'm not talking about the content but about the message. Sometimes slides need to be improved (errors on screen) but often the audio should be recorded once more.
With that being said, the author seems competent in this field. My main problem is only the message.
