Interview Experience: What to Expect

Hey Reader,

another week to crush!

I have something cool to share with you.

Last week, I received an offer from a big company to come in for a tech interview.

Even though I am quite stressed about interviews, I see them as a great opportunity to test my knowledge and find weak spots.

Today, I will share with you my takeaways and, in the end, the questions I was asked.

The interviews I faced could be separated into a few sections:

• Introduction
• Global
• Around the tech stack (Angular, C#)
• Practical Examples

Before we jump into the questions, what are my takeaways and recommendations?

As a self-taught developer coming from smaller teams and projects, I realize more and more that basics are important.

The better code you want to write, the more you need to understand how things work and be effective in optimizing code.

From this, it's not surprising that questions often come up about the difference between various data types like arrays and lists, how the OS works, the structure of networks, etc.

At the beginning, I was speed-running through all the tech to finally build stuff.
​
Now, I am returning often to strengthen my basic knowledge and fill in the gaps.

Just a short tip for you: take your time and learn things well and in depth.

It doesn’t make sense to learn the same principles in 10 technologies.
​
Rather, go with one and learn it in depth.
​
And here questions:
​
- Explain the concepts of OOP.
- Do you know the different types of programming paradigms?
- How does a network work?
- Name and explain some software design patterns.
- Explain the SOLID principles.
- What is the difference between an array and a list?
- What is a pointer?
- What is Angular?
- What are directives?
- What are decorators?
- What is a memory leak?
- Explain HTTP requests.
- What is JWT?
​
Angular example:
- Missing interface.
- Observable not unsubscribed.
​
C# example:
- Missing dependency injection.
- Incorrect naming conventions.
- Wrong Age Calculation.
​
Hope this helps you on yoru coding journey.

Happy coding!
​
Tom
