Technical interviews: How to prepare and succeed

Technical interviews can be challenging, especially in tech and engineering industry. Whether you’re a developer, engineer or analyst, it’s important to know what to expect and how to prepare. With the right approach, you can walk into your interview feeling confident and ready.

What happens in a technical interview?
Technical interviews test how well you solve problems and apply your technical skills. Here are some common parts of a technical interview:

• • Coding challenges: Solve coding problems
  • Whiteboard exercises: Explain how you’d solve a problem by writing code on a whiteboard or using an online tool.
  • System design questions: For senior roles, you may be asked to design a system or architecture.
  • Technical questions: Expect questions about specific programming languages, tools or frameworks.
  • Behavioural questions: Companies also want to know how you work in a team and handle challenges.

How to prepare for a technical interview

• Practise coding problem: Use platforms to practise common coding challenges. Focus on data structures (like arrays and trees) and algorithms (like sorting and searching).
• Learn the company’s tech stack: Research the tools and languages the company uses and brush up on them. If they use JavaScript and React for example, practise coding with those.
• Work on projects: Real experience helps. Share personal or open-source projects to show your skills.
• Practise system design (for senior roles): If you’re going for a senior role, practise designing systems that can scale. Think about performance and how data flows through the system.

Quick tips for interview day

• • Take your time: Read the question carefully before jumping into coding
  • Talk out loud: Share your thinking process as you solve the problem
  • Test your code: Run through a few test cases to check for mistakes
  • Stay calm: Everyone makes mistakes — it’s how you handle them that counts.
