This is the most effective video I have ever seen!! Step1: get the premium subscription Step2: start with the top 100 questions Step3: focus on questions topic by topic Step4: practice with a plan Step5: Solve company specific questions PS: don't look my comment unless you have watched the entire video. I have written just a summary the whole video is explained very well

[@divyathomas7332]

Points from the video: Plan: - First start with the 100 most liked questions. First 50 should be only easy or medium-level questions - Next choose a topic, order the questions from highest to lowest acceptance rate. Solve at least 20 questions or until the patterns "click" before moving on to another topic. Sample list to start off: Binary search, Two pointers, Binary Tree, Backtracking, DFS, BFS, Graphs, Dynamic Programming How to practice: -Start with easy and medium. Go for hard once you know you are ready - Don't spend more than 30 mins on an easy and not more than an hour on a medium. Then if you can't solve on, look at the solution and move on - Learn from the solution. Understand the pattern and techniques. Look at discussion board/ videos to optimize solution and understand better - Revisit questions especially once you couldn't solve - Solve company-specific questions (premium subscription comes useful here)

[@AurelianoShowsTheWorld]

The "-Start" kills me

The most liked questions are the harder even the “easy” ones couldn’t solve under 1h

[@hnwlightsugar2280]

Thank you so much for sharing this! I just solve like 200 questions and most of them were ez, but however I can't do most of them and have to check the solutions, but a few days before I'm starting to find out a way to make the pattern to solve similar questions, like two pointers for array, sliding windows for reducing runtime...etc

[@jim1309]

This video was super useful

[@coderebel3568]

I have a question for you about the time restriction on solving problems.. Why have a time restriction? Yes, I understand that in business, speed is valued by many companies.. But honestly, desire for speed is also what gets the great majority of software companies into trouble because of developers creating bad code that's too coupled, violating principles, buggy, rigid, etc.. Plus, although your customer would sure like you to solve a bug faster rather than slower, they will usually however, still prefer you taking a week, a month, or even a year, to fix something over you not fixing it at all.. They will however not be ok with you creating additional problems for them as a result of fixing something quickly. And doing it anyway will sooner or later damage the customer's trust in you having control over the product. We can conclude then that to a customer, quality of the product (and therefore quality of the source code) is way more important than the speed at which you fix things. As such, me as a developer who had his first experiences in the 1980s on an MSX home computer, I don't give a damn about how fast you are.. I will hire a correct coder over a fast coder any day.. And I think that in order to protect our integrity, we sometimes need to respectfully push back to managers and directors and even customers and let them know the pressure they apply and speed they expect is not good for the product in the long run.. I am therefore very opposed to time limit challenges like this, because it seems to me to reinforce the idea and culture that faster is better.

[@PIRATEKINGDOM]

companies prefer those who can come up with the same solution in a shorter time period. I think they’re willing to risk potential issues for quicker problem solvers

[@coderebel3568]

@@PIRATEKINGDOM I agree they are willing to take some risk.. But are they really aware what risk they are taking and what culture they are introducing? There are developers out there burning out because of anxiety over losing their job, making 14 hour days to compensate for their lack of self-confidence which was inspired by a "beat the clock" culture.. This is bad.. It can ruin a companies reputation and put them out of business.. It's ruining people's lives, making them physically and mentally ill. We have to stop accepting this attitude I think.

[@jykw1717]

Thanks for the video, really helpful. Where do you think is a good place for me to refresh/learn those DS & Algo used for "Focus on topic by topic" section?

Try focusing on the topics you think are the weakest. e.g. Binary Search, Trees, Graphs (DFS, BFS), Dynamic Programming, Backtracking, Recursion, Two Pointers, etc. Out of these, which are the ones that you need to work on the most? Only you can answer that :)

[@PIRATEKINGDOM]

most companies are language agnostic so i don't think they'll care what programming language u use to interview with. if you have the time to learn a new language, then i'd definitely suggest you learn python not only to help you in the interviews but i also think it's just a good skill to have nowadays

[@yashsolanki069]

What programming language did you use in Microsoft interview? Or recommend to use when doing leetcode? Thanks for making this video got my doubts clear on how to solve and not try to be perfect always ✌️👍

[@PIRATEKINGDOM]

I used java. However, companies usually don't care about the language you use for interviews as long as you write readable + understandable code. For leetcoding, I recommend two programming languages: either Java or Python. Java because many of the popular solutions are in Java + sheer number of examples & submissions in LeetCode database already. Python because it's the language that you can solve a LeetCode problem with the least amount of code. Less code -> less prone to error -> faster coding which is critical in real interviews because you have to whip up a working solution within the time limit. Python seems to be more trending nowadays too. More importantly, however, these two are mere suggestions from my experience, but you should ALWAYS use the language you are most comfortable with in actual interviews. Programming language proficiency, I would argue, is the number one thing interviewers look at.
