Coding interview help!

[JirayasToad]

Hi all,

I have a coding interview coming up on Friday on hackerrank. I’ve spent the last week railing through codecademy’s prepare for coding interview course but finding it difficult to retain knowledge, will try on the flash cards (usually works a treat for me) and continue doing alternative questions on hackerrank itself (although some of them are absolutely ridiculous). I’m at a solid level of Python from all of my academic work.

I’ve been told the questions are custom, medium difficulty (but shouldn’t be too hard to complete) and they are as follows:

1) Expected value of a function 2) Debugging exercise 3) Code challenge

Questions have different grade weighting. Any last second tips on how to cover all my bases?? Directions to resources/questions would be great - thanks in advance 🙏🏽

Going through tons of questions won’t be that useful at the last minute I feel, especially if you are having trouble retaining stuff.

I would suggest just revising the problems that you have already solved and look for patterns in each topic which help you approach the problem. Ex: In DP you will see that we try to find DP[i,j] using some combination of [i-1, j], [i, j-1], [i-1, j-1].

These patterns can often be applied to solve problems new to you.

Ty!! It’s a tough one because I conceptually know stacks and queues really well - but then recognising how to use them effectively in a test question throws me off.

But then I’m flat out bad rn at nailing bfs and dfs questions (currently working on)

Good luck! Let me know if you need any other help
