Technical interview questions

If you're applying for jobs in the tech industry, you'll likely attend at least one technical interview. During this type of interview, you'll be asked several technical interview questions that show your skills and abilities. Here we explore what a technical interview is and several questions and sample answers to this type of interview question.

Technical interview defined

A technical interview is one in which a person is applying and interviewing for a job in the information technology (IT) or technology industry. This kind of interview can happen over the phone or in-person and varies in length depending on the type of position being interviewed for. Technical interview questions can vary and may include problem-solving questions, brainteasers, and traditional interview questions that allow the hiring manager to better get to know you and your qualifications, experience, and work ethic.

Technical interviews will also include several technical questions that cover your technical experience and knowledge. Some technical interviews require you to complete an on-site or take-home test that demonstrates your technical skills.

Technical interview questions with sample answers

The following are several example interview questions with sample answers to help you prepare for a technical interview:

How did your education experience prepare you for this position?

While many technology professionals learn their skills through self training, many have also completed a degree at a university or college. Emphasizing your academic achievements and the relevant coursework you did while in school can support your candidacy for a position. Be sure to also mention any additional technical certifications you have received in addition to formal education.

Example answer: During the time spent earning my bachelor’s degree in Computer Sciences, I took several courses that have prepared me for this position. These courses include data logic, computer theory, algorithms, artificial intelligence, and data management. Additionally, I hold the CISCO Certified Network Professional certificate and the Professional Software Developer Certification through the IEEE Computer Society. These certifications allowed me to learn various technology-related skills, including troubleshooting, network planning and implementation, and software design, construction, and testing.

When is the most appropriate time to use SAN?

An interviewer may ask this question to get a better understanding of your specific knowledge as it relates to a certain network you’ll be using if you’re accepted for the position. You should clearly portray your knowledge of this network and how you would use it.

Example answer: SAN is an acronym for Storage Area Network and is a specialized and high-speed network that allows block-level access to technology storage. I would use this network to increase performance, maximize storage space, increase data protection and security, and enhance the availability of the application.

Which programming languages are you most familiar with?

Many technology or IT jobs require in-depth knowledge of one or more programming languages. The most common programming languages used include Java, Ruby, and Python. You can answer this question using the STAR method or by rating your skill level for each programming language.

Example answer: I would say that I am most familiar with Java, as this is the programming language I used on a daily basis in my previous position. In my last job, I was required to create several application interfaces using Java to ensure a user-friendly experience on all platforms. I am also fairly familiar with Python and used this programming language several times in my previous positions.

What does SQL mean and how does it work?

This is another specific question related to database communication that you may be required to use if you’re hired for the position. When answering this question, ensure you clearly portray your understanding of this method of database communication by thoroughly defining it and describing how it functions.

Example answer: SQL is a database that stands for Structured Query Language. SQL is one way of communicating with a database and is considered the standard language for relational database management systems. This language allows you to access and manipulate a database as well as help manage the data held in the database.

How comfortable are you working in an agile workspace?

An agile work environment refers to a workplace that accommodates the various demands of employees. For example, one area of the office may be used for five different purposes throughout the day. Many companies in the IT and technology industries either utilize an agile work environment or are moving towards it, so showing your comfortability and ability to work within this environment may be key for a tech job.

Example answer: My last position was in an office that practiced an agile work environment. Employers were constantly moving from place to place within the workplace, making it imperative that we quickly adapt and move in and out of each space in a timely and efficient manner. This experience allowed me to become more flexible and adapt more quickly to an ever-changing workplace and I feel that I am very comfortable as well as effective when working in an agile work environment.

How do you stay on top of the latest technology industry trends?

Being proactive about your career and staying committed to keeping on top of the latest trends in your industry is an attractive trait to employers. When answering this question, list all of the ways you stay abreast of the changes and trends in the technology or information technology industry.

Example answer: I understand how quickly the technology world is changing, so I make it a point to constantly be up-to-date on the latest industry trends. Ways I do this include by regularly checking out the top technology newsletters, getting updates on the latest trends and news in the industry, following industry social media accounts, and participating in a monthly technology course.

How do you manage source code?

Source control management (SCM) is an important collaboration tool for web developers, and in-depth understanding is necessary for most developer positions. Showing your knowledge of this source code ensures you portray your abilities and know-how of using a prominent tool necessary for the job.

Example answer: I’ve found that the key to managing source code is to successfully manage shared files. The messier the source code, the less easy it is for other developers to quickly interpret a development project. Steps I use when managing source code include choosing a reliable source control system, keeping the source code in source control, reviewing every change, committing often, and making sure all external dependencies are included in the source control.
