What to say in a technical interview?

Technical interviews can be nerve-wracking, but knowing what to say can make all the difference. Let’s break down some key points to help you communicate effectively and leave a great impression.

Start with a Strong Introduction

Begin by briefly introducing yourself. Share your name, your current role or what you’ve been studying, and a quick overview of your experience or interests related to the position.

Example: “Hi, I’m Alex. I recently graduated with a degree in Computer Science and have been working on several projects involving web development and machine learning.”

Clearly Explain Your Thought Process

When tackling problems, verbalize your thinking. This helps interviewers understand how you approach challenges and solve problems.

Steps to Follow:

1. Understand the Problem: Paraphrase the question to ensure you’ve got it right.
2. Plan Your Approach: Outline the steps you’ll take to solve it.
3. Execute the Solution: Write the code or work through the problem while explaining each step.
4. Review Your Work: Go over your solution to catch any mistakes or optimize it.

Example: “So, to solve this sorting problem, I’ll start by implementing a quicksort algorithm because it has an average time complexity of O(n log n). First, I’ll choose a pivot, then partition the array, and recursively apply the same logic to the subarrays.”

Highlight Relevant Experiences

Use your past experiences to demonstrate your skills and how they apply to the role you’re interviewing for. Share specific examples where you successfully used relevant technologies or solved similar problems.

Example: “In my last project, I built a web application using React and Node.js, which improved the user engagement by 30%. This experience taught me a lot about front-end development and managing back-end services efficiently.”

Showcase Your Problem-Solving Skills

Employers are keen on how you handle challenges. Share instances where you faced obstacles and how you overcame them.

Example: “When I encountered a bug that caused unexpected crashes in my application, I used debugging tools to trace the issue to a memory leak. By optimizing the code and implementing better memory management, I was able to resolve the problem and enhance the app’s stability.”

Ask Insightful Questions

Towards the end of the interview, asking thoughtful questions shows your interest in the role and the company. It also helps you understand if the position is the right fit for you.

Questions to Consider:

• “Can you tell me more about the team I’ll be working with?”
• “What are the biggest challenges the team is currently facing?”
• “How do you measure success for this role?”
