Tech interviews are always different, and they are always a little nerve-racking, regardless of which side of the table you sit on. But the best ones, the ones that produce real outcomes and real connections, tend to share common patterns.
This article covers six of those patterns. Each one is written from both perspectives: what the candidate should focus on, and what the employer should get right. Because a good interview is a two-way process, and both sides have work to do.
1. Start with preparation
For candidates. Your preparation is your foundation. Research the company’s website, Glassdoor, Teamlyzer (in Portugal), and Indeed to understand the product and the role. Check how your experience maps to what they are looking for. Do not just prepare for what you think they will ask. Try to anticipate what you would ask if you were on the other side. Practise your answers beforehand and make sure you can tell a clear story. Prepare specific examples that show your experience, your role in each situation, and the skills you developed.
For employers. Build a solid interview structure. You need to be ready to share the company story, the role in detail, and a genuine reason why the candidate should join you. Real engagement with the candidate starts in this first meeting. The interview is not just about asking questions, it is about knowing how to present your opportunity. Prepare questions that dig into the specifics of what you need. Good preparation keeps you focused and prevents the conversation from drifting.
2. Communication can make or break it
For candidates. Communicate clearly and honestly. If you do not know something, say so and show that you are willing to learn. Employers respect humility and curiosity more than a fumbled answer. Make sure the conversation flows naturally. The best interviews feel like genuine conversations, not interrogations.
For employers. Be explicit about what the role involves, what the culture is like, and what you are looking for. Clarity helps candidates give better answers and sets the stage for a transparent relationship from the start. Tech is still a candidate-driven market. In most situations, talent chooses you, not the other way around. How you communicate and present your project is critical to attracting the strongest candidates.
3. Cultural fit matters more than you think
For candidates. Be yourself. The best way to find the right job is to be honest about who you are and what you want. If a company’s culture does not feel right, it is better to walk away than to settle and leave after a few months. Pay attention to how you connect with the hiring manager and your potential team lead. If something feels off, trust that instinct.
For employers. Showcase what makes your organisation distinct: your values, your working environment, your model, and the real benefits of working with you. Candidates want to know they are joining a place that aligns with their own values, where they will be respected and where they can genuinely grow. Your employer brand is doing half the selling before the interview even starts.
4. Technical rounds are there for a reason
For candidates. This is where you demonstrate what you can do. Show your skills, but do not forget to explain your thinking clearly. Employers are looking at how you approach a problem, not just whether you get the right answer.
A few ways to prepare:
- Check the tech stack the company uses. Look at employee GitHub profiles to understand what tools and frameworks they work with, and reference similar work from your own experience
- Brush up on core computer science fundamentals: algorithms, design patterns, data structures. These come up in most technical interviews regardless of the stack
- If the process includes coding exercises, practise on platforms like LeetCode, HackerRank, or CodeSignal
- For systems design interviews, be ready to walk through architecture decisions and explain your reasoning
For employers. Use technical challenges to assess real-world skills, not abstract puzzle-solving. Make the tasks relevant to the actual work the person would do. Use them to see how a candidate thinks and solves problems, not just whether they can perform under artificial pressure.
5. Questions need to flow both ways
For candidates. Ask your own questions. It shows genuine interest and gives you the information you need to make your own decision. Ask about the team’s composition and culture, the challenges of the role, the project’s objectives, and the growth opportunities. What you ask tells the interviewer what matters to you. If you have nothing prepared, it can read as indifference.
For employers. Your questions should reveal the depth of a candidate’s experience. Ask about past projects, how they handled specific challenges, and how they approach problem-solving. You are looking for substance and resourcefulness. Include personal questions too: how they work in a team, what they enjoy outside work, what motivates them. Cultural fit is as important as technical fit, and you can only assess it by getting to know the person.
6. The interview is the start of a relationship
For candidates. The process is a two-way street. It is not just about getting this job, it is about making connections that could matter in the future. Follow up with a thank-you note. Stay in touch even if it does not work out this time. Be ready to show how you adapt to new technologies and evolving environments. Employers want to know that you will keep pace and push yourself to stay current.
For employers. You are trying to find someone to join your team and work alongside you every day. Even if a candidate is not the right fit now, they might be later, or they might recommend someone who is. Treat every candidate with respect and leave them with a positive impression of your company. With all the automation tools available today, do not lose the human element in the process. It is the thing candidates remember.
Interviews are always different. But the ones that work, for both sides, tend to share the same qualities: real preparation, honest communication, mutual respect, and a genuine curiosity about the person on the other side of the table.
