In this video we go through the steps of how to solve the CodeSignal Interview Prep array challenge entitled: firstDuplicate.

In this video I use Kotlin to solve the challenge, but CodeSignal allows you to choose other languages if you'd like. The overall solution should be transferable to any language.

I chose to code this live-ish, meaning, I didn't really have a solution figured out in my head. I think it's helpful to really deal with pressure even when you're just practicing.

Apologies about the background noise and terrible audio quality. Hopefully this was helpful!

This is how I would prepare for those hard coding interviews if I were to do it all over again. I would optimize my time, follow a schedule and learn data structures and algorithm fundamentals before diving into any programming interview question. The truth is getting a software engineering job is hard and it takes a lot of studying and dedication but it's worth it. The stuff you learn in a computer science degree is very theoretical and it doesn't always translate to coding interviews.

Hi everyone,
I recently did this test for Data Engineer position at RBC through CodeSignal Platform. These are the practice tests, not the real questions (I signed the NDA so I can't disclose the real questions). There are 4 questions for total of 1 hour and 10 minutes. I didn't finish question 3 and didn't even touch question 4.
I also attached my solutions (not optimal) in the end of q1,q2 for your references.
If you would like me to analyze and explain all these questions, please like and comment below.

In this live demo, we show how you can use CodeSignal to run data science technical interviews.
