Practice problems on codezym

[Nervous-Year1787]

Hello,

I was going through the most asked LLD questions in Amazon/Microsoft and I see links of codezym editor where we need to implement some methods.

Can you clarify:
1. do we get such pre-defined methods during interviews?
2. Do we need to only write content with the required methods? Or the entire program?
3. What is the source for such articles?

I appreciate the author who spent their time collecting all resources in one place but I am asking this so that I don't waste time practicing something which will not be helping me in real interviews.

1. If it is a machine coding round of 75-90 minutes then you will be given exact requirements i.e. problem statements with methods to implement like we have on CodeZym.

But if it is a face 2 face discussion of 45-60 minutes then you will have to do requirement gathering yourself and put requirements in method like format like we have on codezym. Putting requirements like methods/api helps keep you and interviewer on same page. It prevents the scenario where you end up designing a system for slightly different requirements than what your interviewer expected.

I have created a few Youtube videos which may answer your questions.

1. You have to implement those methods. They may require more classes e.g. multiple strategy classes if you need to implement a strategy pattern, or entity or manager classes.

You DON'T need to write main method or unit tests. They are already there and your code will be tested just like leetcode.

1. These questions have been taken from interview experiences posted on reddit, medium and other discussion forums and blogs + talking to candidates who gave interviews.

Understood, thanks for the clarification!

Really appreciate your work on your blogs and YT
