What does a technical interview look like?

Technical interviews are a key part of landing a job in the tech industry. They evaluate your problem-solving abilities, technical knowledge, and how you handle challenges. Let’s break down what a typical technical interview looks like so you can approach it with confidence.

Types of Questions

Technical interviews usually include a variety of question types to assess different skills.

Coding Problems

You’ll be asked to solve coding challenges that test your understanding of data structures and algorithms. These problems evaluate your ability to write efficient and correct code under time constraints.

System Design Questions

For more experienced roles, system design questions are common. These assess your ability to architect scalable and robust systems. To get a solid grasp on this, check out Grokking System Design Fundamentals.

The Interview Structure

A typical technical interview may follow this structure:

1. Introduction: The interviewer introduces themselves and outlines what to expect.
2. Warm-up Questions: Simple questions to get you comfortable.
3. Main Questions: These include coding problems or system design scenarios.
4. Behavioral Questions: Some interviews include questions about your past experiences and how you handle different work situations.
5. Your Questions: At the end, you’ll have the chance to ask questions about the role or the company.

What to Expect During the Coding Portion

When tackling a coding problem, here’s a common flow:

• Understand the Problem: Make sure you fully grasp what’s being asked. Don’t hesitate to ask clarifying questions.
• Plan Your Approach: Outline your solution before writing code. This helps in organizing your thoughts.
• Write the Code: Implement your solution while explaining your thought process.
• Optimize and Test: Review your code for improvements and test it with different cases.
