What Is an Interview? Types, Formats, and How to Prepare

An interview is a structured conversation between two or more people where one side asks questions and the other provides answers, typically to evaluate fit for a job, gather information, or make a decision. While the term applies in journalism, research, and other fields, most people encounter interviews during the hiring process, where an employer assesses whether a candidate has the right skills, experience, and personality for a role. Importantly, an interview works both ways: you’re evaluating the employer just as much as they’re evaluating you.

How a Job Interview Works

At its core, a job interview is a conversation with a purpose. The employer wants to learn whether you can do the work, whether you’ll mesh with the team, and whether your goals align with what the company offers. You, in turn, want to find out if the role matches your skills, if the work environment suits you, and if the compensation is fair.

Most hiring processes follow a predictable sequence. You apply, someone reviews your resume, and if there’s a match, you’re invited to an initial interview. That first conversation is often a screening call lasting 15 to 30 minutes, where a recruiter confirms basic qualifications and interest. If you pass, you move to one or more in-depth interviews with hiring managers or team members. Some companies add a final round with senior leadership before extending an offer.

Throughout this process, the quality of the interaction depends heavily on rapport. Active listening, clear communication, and genuine curiosity on both sides turn a stiff Q&A session into a productive exchange. The best interviews feel less like an interrogation and more like a focused professional conversation.

Common Interview Formats

Not all interviews look the same. The format depends on the industry, the role, and what the employer is trying to learn about you.

  • Behavioral interviews focus on how you’ve handled real situations in the past. The logic is simple: past behavior predicts future behavior. Expect questions like “Tell me about a time you resolved a conflict at work” or “Describe a project where you had to meet a tight deadline.” Your answers should include specific examples with concrete results.
  • Technical interviews test job-specific knowledge. Software engineers might be asked to write code on a whiteboard or in a shared editor. Accountants might work through a financial scenario. These interviews measure whether you can actually do the work, not just talk about it.
  • Case interviews are standard at consulting firms. You receive a business problem and walk through your analysis out loud. The interviewer cares less about the “right” answer and more about how you structure your thinking and work through ambiguity.
  • Panel interviews put you in front of multiple interviewers at once. Each panelist typically represents a different perspective, such as a direct manager, a team member, and someone from HR. These save time for the company but can feel more intense for candidates.

Many companies use a combination. You might start with a behavioral phone screen, move to a technical assessment, and finish with a panel interview on-site.

Virtual, In-Person, and Hybrid Interviews

Where the interview happens matters almost as much as what’s asked. In-person interviews take place at the employer’s office, giving you a chance to see the workspace, meet potential colleagues, and get a feel for the company culture. They also require travel, which can mean commuting across town or flying to another city.

Virtual interviews happen over video platforms like Zoom, Google Meet, or Microsoft Teams. No travel is needed, which makes scheduling easier and opens doors for candidates in different cities or time zones. The tradeoff is that reading body language and building personal connection can be harder through a screen. To prepare, make sure your camera, microphone, and lighting work well, choose a quiet background, and test your internet connection beforehand.

Many employers now use a hybrid approach: early rounds happen virtually, and finalists are invited on-site for a final conversation. This balances efficiency with the deeper connection that comes from meeting face to face.

AI and Automated Screening Interviews

Some companies, especially those hiring at high volume, use automated video interviews as an early screening step. Instead of speaking with a live person, you record yourself answering preset questions on a platform. Your responses may be scored by software that evaluates factors like communication clarity and relevance to the question.

AI-powered tools also show up in other parts of the process. Some platforms auto-score technical assessments, including coding challenges, so even non-technical hiring managers can evaluate candidates. Others handle scheduling automatically, syncing with interviewers’ calendars to eliminate the back-and-forth of finding a time that works.

If you’re asked to complete an automated interview, treat it with the same seriousness as a live conversation. Dress professionally, look at the camera rather than the screen, and give structured answers. The recording is reviewed by real people in most cases, even when AI helps with initial scoring.

How to Prepare

Preparation is the single biggest factor separating candidates who get offers from those who don’t. Start by researching the company: understand what it does, who its customers are, and what challenges it faces. Then review the job description line by line and think of specific examples from your experience that demonstrate each listed skill or responsibility.

Practice answering questions out loud. Behavioral questions in particular benefit from a simple framework: describe the situation, explain what you did, and share the result. Keep your answers focused. Two minutes per question is a good target for most responses.

Prepare your own questions, too. Asking thoughtful questions about the team, the role’s priorities, or how success is measured signals genuine interest and helps you decide if the job is actually right for you. Avoid questions you could answer with a quick look at the company’s website.

What Interviewers Are Evaluating

Beyond your technical qualifications, interviewers pay attention to how you communicate, how you think through problems, and whether you seem genuinely interested in the role. They’re also assessing cultural fit, which really means whether your working style and values align with the team’s.

Fairness matters on the employer’s side. Best practices call for asking every candidate the same core questions and using a standardized rating system to keep assessments consistent across interviews. If you notice that an interview feels unstructured or the questions seem random, that can be a signal about how organized the company is more broadly.

Finally, remember that the interview is a two-way evaluation. Pay attention to how the interviewer treats you, whether they’re prepared, and how they describe the day-to-day reality of the job. The way a company conducts its interviews often reflects the way it treats its employees.
