So you’re thinking about taking the plunge and applying for tech jobs? Open the laptop and crunch those codes to prepare for those challenging interview questions. 

Well, good news: this article is about a platform called LeetCode. It can provide tips on getting started and boost your chances of success in a tech interview.

But what is the platform all about? What is its purpose? And is it worth it?

Read on to learn more.

What is LeetCode?

LeetCode is a crowdsourced cheat sheet for practicing solving coding difficulties and preparing for technical interviews. The company was founded in 2015 by Winston Tang.

LeetCode is a platform that allows people to share and collaborate on code challenges. Anyone anywhere can join in on the fun, whether they’re a developer, a tech enthusiast, or want to learn something new. 

There are hundreds of LeetCode challenges available, covering everything from coding fundamentals to more advanced topics. 

And best of all, there’s always room for more. If you’ve got a programming problem you need to be solved, LeetCode has the code for you.

Is LeetCode tough?

LeetCode is tough; it’s intense.

You’ll be up all night. But you won’t regret it. You’ll come back for more. LeetCode tests your skills to the fullest. 

You’ll need to use all your knowledge and Google search skills to solve as many problems as possible. And it’s not just about solving problems – LeetCode also demands creativity and critical thinking. 

People who like to solve complex problems are drawn to LeetCode. It’s the kind of place where you can take on any challenge and beat it. 

Whether coding the perfect algorithm or solving a complex problem, LeetCode is about pushing yourself to your limits. 

And that satisfaction comes from knowing you’re one step closer to becoming a world-renowned coder or working with the tech company of your dreams. 

So whether you’re a novice programmer or a prodigy, LeetCode is your place.

Why are coding interviews so hard?

Coding interviews are one of the most difficult parts of the job search process. Interviewers want to know that you’re a problem-solver and comfortable with debating assumptions. 

They also want to know your motivation for wanting to become a coder. Interviewers may ask difficult coding questions and require you to code complex scenarios. 

If you aren’t prepared for these challenges, you’ll struggle and may be unable to answer questions quickly or accurately. 

A poorly performed coding interview can impact your chances of getting the job.

  • Coding interviews are subjective and based on vague concepts like “programming abilities”
  • Interviews are time-consuming; they overestimate the skills of an average developer
  • Optimizing for how quickly you write code is not the same as optimizing for how good your code ends up being
  • Some of the interviewers are aware of LeetCode, so they use it to your disadvantage

So whether you’re interviewing with a startup, a big corporation, or even an individual company, make sure you’re well-prepared. 

Take some time to practice coding questions and scenarios, and be confident in your answers. 

With a little preparation, you’ll easily sail through your coding interview and secure the right position.
