Questions about the technology, processes, and procedures used in a job are known as technical questions. Like operational questions, interviewers use technical questions to confirm your knowledge and experience related to the job. When responding to a technical question, you should keep your answer brief and to the point and only provide the information the interviewer is asking you about. They will ask a follow-up question if they need additional information.
