Technical interviews are still a key part of the hiring process in IT — whether you’re applying as a developer, tech support agent, QA tester or systems engineer. These interviews test your problem-solving skills, technical know-how, and how well you think on your feet.
But here’s the good news: with the right preparation, you can turn stress into confidence. Let’s walk through 4 essential tips to help you make a strong impression and land the job.
Start by reviewing the job description — it’s your cheat sheet. What tools, languages, or platforms are mentioned? That’s your study list.
Most tech interviews will touch on one or more of these areas:
Computer Science fundamentals: Be ready to talk about algorithms, data structures (like trees, stacks, or linked lists), and basic logic.
Programming skills: Know your go-to languages (JavaScript, Python, Java, etc.) and be able to explain your code. Even better if you can write a short function live.
General tech knowledge: Depending on the role, you might get questions about systems architecture, APIs, network basics, or DevOps tools.
This is your moment to show that you not only know the theory — but that you own it.
Practicing before the real deal makes a huge difference. Online platforms let you simulate real interviews so you can train under pressure and get used to the type of questions recruiters ask.
Here are some free (and super useful) platforms:
InterviewBit – Great for practicing technical questions from top companies.
LeetCode – A favorite among engineers interviewing at Google, Meta, Amazon.
CodeWars – Offers fun coding challenges in 50+ languages to sharpen your skills.
Pro tip: Use these platforms not just to memorize answers — but to improve how you explain your logic clearly and confidently.
If the role mentions specific tools, languages, or platforms — get your hands dirty. Build a small project. Solve some problems. Review your past work. Anything you can refer to during the interview gives your answers credibility.
Not sure what to focus on? Start with the tech stack mentioned in the job ad. For example:
For a tech support role: brush up on troubleshooting, ticketing tools, basic scripting.
For a developer role: focus on writing clean code, debugging, version control (Git), etc.
For QA: get ready for test case writing, bug tracking, automation frameworks.
Be ready to talk about salary — yes, even in the first interview. Research current market rates for your role, experience level, and location.
Websites like Glassdoor, Levels.fyi, or Payscale can help you benchmark your expectations. Don’t sell yourself short — but also be realistic and flexible.
Knowing your worth will make you feel more confident and prepared when the recruiter brings it up.
Tech interviews can be intense — but they’re also your chance to shine. Take them as an opportunity to show off your problem-solving mindset, your passion for tech, and how well you communicate under pressure.
Remember: confidence is built through preparation.
Good luck — you’ve got this!
