What is a technical interview?

A technical interview refers to a job interview for any job role or position in the tech industry. These positions may include those like information technology, technical support, technical analysts or software developers. Most technical interviews usually take place physically in person, but in recent times, many of them may switch to online interviews over video calls. Tech interviews may also comprise traditional interview questions, problem-solving questions, technical proficiency tests or personality assessments.

During the technical interview, the hiring manager or interviewer may test your technical knowledge, skills and abilities related to what you may require doing in the job role you're applying for. Along with testing your technical skills and knowledge, the hiring manager and interview may also want to find out how you solve problems during test situations and what your thought process is when solving these issues. Some interviewers may also want to know more about your personality to see if you fit into the company's culture and environment.

At the same time, this helps me apply my C++ skills and knowledge to personal use while improving on them for professional projects.'

Interviewers may ask you technical questions like this to truly access your knowledge in the technology sector. These questions may also be for interviewers to find out if you have the technical skills the company is looking for in their projects.

Example: 'JavaScript is a programming language that I work with often in my previous roles. In my experience with JavaScript, I feel that there are many advantages to this programming language. First, it requires less server interaction and you can validate any user input before sending the page into the server, which means less load on your server. Second, you don't require waiting for your page to reload with JavaScript since it gives you immediate feedback, helping you save time. Last, JavaScript is very interactive, helping you create interfaces that can react with users and making it more engaging.'
