The technical interview is a job interview that aims to test your technical knowledge, generally related to that required by the role you are applying for.

It is very common to evaluate candidates for open positions in the fields of science, information technology, and engineering. The recruiter is in fact focused on evaluating your practical skills, necessary in the position you are potentially going to fill in the company.

Some technical interview questions are less about your knowledge and more about how you think. These questions are asked to assess your problem-solving skills or your ability to reason with numbers and variables.

This means that the recruiter may ask you to solve some puzzle or reasoning test. Not all technical interviews take place face to face; some can be done by phone, while others can be via video call, for example, with Skype. Let’s see what to expect and how to prepare for a successful technical interview.


What does the recruiter want to know in a technical interview?

The first thing the recruiter wants to make sure is that you have the right technical skills: that is, the basic knowledge required to best perform the proposed role, as well as your familiarity with different tools and technologies in that industry.

The recruiter also wants to judge your ability to apply these skills to real-life situations in the workplace.

However, testing your technical skills is not the only purpose of this interview. The recruiter will also try to understand how you cope with problem-solving and communication strategies, and therefore, how you reason and how you communicate your reasoning during the interview.

The recruiter wants to know your personality and your way of explaining and illustrating how you analyze situations, especially if the role offered involves you giving presentations, writing reports, and offering technical assistance.

Remember that the interviewer is not looking for a correct answer, they are more interested in observing the reflections you make to arrive at the answer. It will then evaluate your analytical skills, your lateral thinking, and your creativity.

A key part of the technical interview is about your way of looking for answers and solutions to problems that you have never faced before.

Like in a traditional job interview, your ability to cope with stressful situations will also be judged. The recruiter will try to understand how you work under pressure and will test you to find out.

20 Tips and Tricks for Your Next Engineering Job Interview

During the technical interview

As we mentioned, this type of interview is not based on evaluating only your technical know-how, but also on your way of interacting and communicating your reasoning.

One of the things that can lead candidates to be excluded from the selection is their inability to formulate sensible answers to questions. Many have a clear answer in their heads but do not know how to articulate it and explain the arguments made.

Try not to get confused: some questions are designed to gauge your reactions and aim to openly challenge you; the recruiter probably doesn’t even expect you to know the answer!

Before answering, take a deep breath and try to find the answer based on your skills, logic, and creative thinking. The recruiter wants to see how you handle a difficult question or problem, rather than checking if you have the correct answer. Always try to answer, no matter how difficult the question may seem to you.

If you’re in too much trouble and don’t know what to say, tell the recruiter. It is much better to admit that you don’t know what to say instead of being silent or giving answers that don’t make sense. If you don’t understand the question, always ask for clarification to dispel your doubts. Also, remember to ask the recruiter questions when he asks you “Do you have any questions for me?”. Clarify your ideas about the role and the company. Asking questions is also a great way to show your sincere interest.

At the end of the interview

At the end of the interview, ask the recruiter to give you the answers to the questions you answered or ask how he/she would have solved the problem. This will show the recruiter your willingness to learn from your mistakes and learn new things.

Furthermore, if you decide to follow up after the interview, or send the recruiter an email to thank him and reiterate your interest in the position, you can include the answer to a question that you were unable to solve during the interview. / p>

Don’t worry if you make mistakes during the interview. Everyone makes mistakes, so don’t fret. If you realize you have done something wrong, you can correct your position at the end of the interview and explain to the recruiter how you would have answered more correctly.

Either way, as long as you can keep your nerve, show confidence, and prepare effectively for the interview, you’ll be able to tackle and handle even the most intricate questions of the technical interview.
