One of the best ways to prepare for coding interviews is by studying coding mock interview examples. 

There are a lot of free videos out there but it’s hard to know what language they’re actually using without watching them.

In the article below, we’ve listed the best mock interviews available on YouTube for the most common coding language. 

We hope this list saves you time!

6. How to prepare for coding interviews

One of the main challenges of coding interviews is that you have to communicate what you are doing as you are doing it. Having to think, code, and communicate your thoughts to the interviewer all at the same time is not easy.

With that in mind, don't let the first interview you do be the real thing. Instead, we highly recommend getting some mock interviews under your belt.

6.1 Practice with peers

If you have friends or peers who can do coding mock interviews with you, that's an option worth trying. It’s free, but be warned, you may come up against the following problems:

  • It’s hard to know if the feedback you get is accurate
  • They’re unlikely to have insider knowledge of interviews at your target company
  • On peer platforms, people often waste your time by not showing up

For those reasons, many candidates skip peer mock interviews and go straight to mock interviews with an expert. 

6.2 Practice with experienced coding interviewers

In our experience, practicing real coding interviews with experts who can give you company-specific feedback makes a huge difference.

Find a coding interview coach so you can:

  • Test yourself under real interview conditions
  • Get accurate feedback from a real expert
  • Build your confidence
  • Get company-specific insights
  • Save time by focusing your preparation

Landing a job at a big tech company often results in a $50,000 per year or more increase in total compensation. In our experience, three or four coaching sessions worth ~$500 make a significant difference in your ability to land the job. That’s an ROI of 100x!
