The Interview Sage

I am currently preparing for my upcoming software engineering interviews. Thus, I started writing two series on cracking the Behavioral and System Design Interviews at major tech companies as it helps me gather my knowledge in one place. And it also helps others in preparing for their interviews ๐Ÿ™‚

This week I wrote the following article in the Behavioral Interview series:

I discovered the Mikado method that helps me refactor a very old codebase. Like in the game for kids, the idea is to find out the easiest stick you can move without breaking lots of stuff. I've only read two chapters so far but I had a "Aha" moment already

The Mikado Method is a process for surfacing hard-to-see dependencies in a codebase. It is very useful when you are trying to change a codebase, eliminate technical debt and get things done while keeping focus on creating business value.The Mikado Method is a process for surfacing hard-to-see dependencies in a codebase.

I learned about docker which creates an environment container for my app to run in. Great for different team members who uses different OS. I did learn about how to use the GraphCMS to do content modeling and create my category and product queries. Also graphql codegen to create my types and my calls via my graphql files and schema so now I have my product pages statically generated with Next.js. On a conceptual level, I did look into the SOLID principle for OOP. Also learned about spies and stubs for mocking purposes. My goal next week is hopefully get react hooks form, stripe, the email service implemented in the app with the addition of using CMS web hooks for emailing when a new product comes out or when the order is created and at least get an MVP project.

I learnt about using Assertion Scope in C# with Fluent Assertions.

TLDR; If you write a test that uses multiple assertions, you can check the result for all of them at once using a Assertion Scope rather than having to fix your code each time your test fails on a Assertion!

I think it'll need to be my next #csharp blog post ๐Ÿ˜Š

This week at work I learned (with the help of my awesome new teammate) about setting up eslint + Prettier in a new Angular 12 project. At home I have continued to tinker with my Neovim configuration and now have something that feels pretty usable.

Since I'm always curious to design things, so I made my own VS Code theme extension this week and added colors that match my desktop setup. I have made a blog too this Sunday. Here is the link:
