Interview Formats to Use When Hiring
If there’s one truth I’ve learned after spending decades in the staffing world, it’s this: the way you interview is just as important as who you interview. I’ve seen phenomenal candidates get passed over because the interview format didn’t showcase their strengths, and I’ve seen lackluster hires slip through because the format wasn’t rigorous enough.
Early in my career, I treated interviews like a checklist: schedule the phone screen, meet face-to-face, shake hands, hire (or not). However, as our clients became increasingly diverse, from tech startups to healthcare giants, it became clear that a single, cookie-cutter approach was no longer sufficient. Roles evolved. Candidate expectations changed. And so did the interview process.
Today, interview formats are as varied as the roles we recruit for. From structured interviews that score every answer to real-time problem-solving sessions that mimic the actual job, each format offers unique advantages and pitfalls. The key is knowing when to use which.
In this guide, I’ll walk you through the most effective interview formats I’ve used and implemented for hundreds of hiring teams. I’ll break down what each is, where it works best, and the real-world lessons I’ve learned along the way.
What Are Interview Formats?
Think of interview formats like tools in a hiring manager’s toolkit. Some are precise, like a laser level, structured, repeatable, and designed to remove bias. Others are more fluid and intuitive, giving you a chance to “feel out” a candidate’s personality or creativity.
At their core, interview formats are the structures we use to evaluate talent, the frameworks that shape the questions we ask, how we assess answers, and the overall candidate experience within our company.
Choosing the right format isn’t just about preference; it’s about purpose. Are you hiring a sales rep who needs to think on their feet? A software engineer who’ll be judged on technical acumen? A VP who needs cultural alignment as much as credentials?
I’ve worked with hiring managers who relied too heavily on their gut instincts, and others who conducted interviews so rigidly that they felt like interrogations. In both cases, the format failed the candidate and the company.
The best interview formats strike a balance: they give candidates a fair chance to demonstrate their abilities while providing hiring teams with the structure they need to make informed decisions.

The Difference Between Interview Formats and Interview Styles
This is a distinction I often find myself explaining to clients, more often than you might think, and it’s a critical one. While interview formats and interview styles are frequently used interchangeably, they’re not the same thing. Understanding the difference can help you design a more effective and candidate-friendly hiring process.
Let’s start with interview formats. These are the structural blueprints of your interviews, the tangible setup. Are you doing a one-on-one? A panel? A phone screen? A technical test? These are all formats. They answer the “how” of your interview process.
On the other hand, interview styles refer to the tone and technique you bring to that format. Are your questions structured and consistent across candidates? That’s a structured style. Do you prefer a more conversational, open-ended approach? That’s unstructured. Are you focused on past behavior (behavioral style) or hypothetical scenarios (situational style)?
In short:
- Format = Structure (how the interview is conducted)
- Style = Method (how questions are asked and assessed)

Top Interview Formats Explained
Let’s dive into the formats that make up the foundation of most successful hiring strategies. For each, I’ll share what it is, when to use it, the advantages, and the drawbacks.
One-on-one interviews
This is the classic format, the one we all picture when we think of a job interview. One-on-one interviews are exactly what they sound like: a single interviewer meeting individually with a candidate, either in person or virtually. They’re personal, direct, and, when done well, an invaluable way to build rapport and dive deep.
Don’t be fooled by the simplicity, though. One-on-ones can be wildly effective or a total waste of time, depending on how intentional the interviewer is.
When to use it:
- Early in the process for screening or initial rapport-building
- As a follow-up to panel or technical interviews, to dig deeper
- For roles where a strong working relationship with one manager is key
Pros:
- Allows space for authentic, human connection
- Easier for candidates to relax and open up
- Interviewer can tailor the conversation based on live cues
Cons:
- Risk of bias or subjectivity if no structured guide is used
- Limited perspective—just one person’s interpretation
- Can miss red flags if not paired with other formats
Panel interviews
At first glance, panel interviews can be intimidating for both candidates and interviewers. Sitting across from three, four, or even five people firing off questions is a lot. However, when executed well, panel interviews provide a holistic and efficient way to evaluate a candidate from multiple perspectives in one sitting.
In this format, a group of interviewers (usually from different departments or functions) meets with the candidate at the same time. It’s ideal for roles that require cross-functional collaboration or alignment with stakeholders.
When to use it:
- Leadership roles that interact across departments
- High-stakes or high-volume hiring where efficiency matters
- When multiple team members need buy-in on the final decision
Pros:
- Offers diverse perspectives in a single session
- Cuts down on time-to-hire by consolidating interviews
- Helps assess how candidates handle pressure and group dynamics
Cons:
- Can feel overwhelming or performative for some candidates
- Risk of inconsistent evaluation if the panel isn’t aligned on criteria
- Requires coordination and prep to avoid overlapping or redundant questions

Group interviews
Group interviews involve multiple candidates being interviewed simultaneously, either interacting with each other or responding to a single interviewer or a panel. This format is often used in high-volume hiring environments or for roles that require collaboration, competitiveness, or public speaking as key components of the job.
When done right, group interviews are a goldmine of insight: you see how candidates perform under pressure, how they interact with peers, and who naturally takes the lead. When done poorly? It can feel like a cattle call.
When to use it:
- High-volume hiring (retail, customer service, seasonal roles)
- Positions that require teamwork, leadership, or public interaction
- Early-stage screening when time and resources are limited
Pros:
- An efficient way to evaluate multiple candidates at once
- Reveals communication and group dynamics in real time
- Helpful in observing natural leadership, assertiveness, and collaboration
Cons:
- Can be intimidating and unfair to quieter candidates
- Difficult to assess individual contributions in large groups
- Not ideal for roles requiring deep technical or individual focus

Phone interviews
Quick, convenient, and low-pressure phone interviews are the unsung heroes of the hiring funnel. While they may lack the visual cues of in-person or video conversations, they’re incredibly useful for initial screening and narrowing the field without a major time investment.
I often recommend phone interviews as a first-pass filter to assess basic qualifications, communication skills, and overall fit before bringing someone in (or online) for a more in-depth discussion.
When to use it:
- Early screening for high-volume roles
- Remote hiring when video isn’t necessary yet
- When you want to focus on content over charisma
Pros:
- Fast and efficient (great for busy hiring teams)
- Reduces visual bias and allows focus on what’s said
- Easier scheduling for both sides
Cons:
- No body language or facial expressions to read
- Can feel impersonal or transactional
- May disadvantage candidates who aren’t strong verbal communicators

Video interviews (live & pre-recorded)
If there’s one format that exploded in the last few years, it’s this one. Video interviews, both live and pre-recorded, have become essential for remote hiring, distributed teams, and time-strapped recruiters. They bridge the gap between phone screens and in-person interviews, offering both efficiency and face-to-face interaction (virtually, of course).
There are two main types:
- Live video interviews, which are essentially Zoom/Teams calls
- Pre-recorded video interviews, where candidates record responses to set questions on their own time
Each has its place, and both have changed the game in terms of flexibility and reach.
When to use it:
- Remote or hybrid hiring processes
- Early-stage screening with large candidate pools (pre-recorded)
- Mid- or final-round interviews when travel isn’t feasible
Pros:
- Convenient for both candidates and interviewers
- Expands access to geographically diverse talent
- Pre-recorded options save time and allow for consistent evaluation
Cons:
- Tech issues can disrupt the experience
- Harder to build rapport or read subtle cues
- Some candidates may find pre-recorded interviews awkward or impersonal

Technical interviews/skill assessments
When you’re hiring for roles that require specialized expertise, whether it’s writing code, troubleshooting systems, or analyzing data, you need more than a good conversation. You need proof of skill. That’s where technical interviews and skill assessments come in.
These interviews go beyond soft skills and resume claims. They challenge candidates to demonstrate what they know and how they think. Sometimes it’s a live coding session. Sometimes it’s a take-home challenge. Other times, it’s a whiteboard problem in front of a panel.
When to use it:
- Engineering, IT, data science, and other technical fields
- Roles where hands-on problem-solving is central to success
- When screening for both technical accuracy and problem-solving approach
Pros:
- Offers objective insight into a candidate’s real abilities
- Helps differentiate between great talkers and great doers
- Can be tailored to reflect actual on-the-job tasks
Cons:
- Time-consuming to create and evaluate effectively
- Risk of bias if scoring isn’t standardized
- Can be stressful or feel performative for candidates, especially live
Case interviews
Case interviews are where logic meets business strategy. In this format, candidates are presented with a hypothetical business problem and asked to walk through how they’d solve it. It’s less about arriving at a “right answer” and more about understanding how a candidate thinks, structures problems, and communicates under pressure.
This format is commonly used in consulting, product management, finance, and executive-level hiring, anywhere strategic thinking and decision-making are critical.
When to use it:
- Strategic or analytical roles (consulting, product, operations, finance)
- Senior-level hires who will influence or drive decisions
- When you want to evaluate structured thinking, data literacy, and business acumen
Pros:
- Reveals critical thinking, creativity, and structured problem-solving
- Tests real-world decision-making, not theoretical knowledge
- Helps assess how candidates handle ambiguity and pressure
Cons:
- Can be intimidating or unfamiliar to candidates outside of consulting
- Requires preparation to deliver consistently and fairly
- May disadvantage candidates who aren’t trained in case formats but still excel in real roles
Job auditions
This is where theory meets reality. In a working interview, candidates are invited to perform real or simulated job tasks, either in the actual workplace or in a controlled, time-boxed setting. Think of it as a test drive for both the candidate and the employer.
I often recommend the job audition format when hiring for roles that are difficult to evaluate through conversation alone, such as creative positions, administrative roles, or skilled trades. It’s also a fantastic option when team dynamics and task execution are just as important as technical ability.
When to use it:
- Roles where performance is best assessed through hands-on tasks
- Situations where culture fit and team interaction are critical
- When hiring for detail-oriented or deadline-driven positions
Pros:
- Offers a clear view of real-world capability
- Helps assess how candidates interact with team, tools, and tasks
- Reduces hiring risk, especially for high-stakes or high-turnover roles
Cons:
- May require compensation or legal precautions depending on local labor laws
- Can be time-intensive to coordinate
- Risk of poor candidate experience if expectations aren’t clear
Multiple-round interviews
Multiple-round interviews are exactly what they sound like: a series of interviews, each with a different purpose or audience. This format is standard in mid-to-senior level hiring, where one conversation simply isn’t enough to make a confident decision.
The benefit of multiple rounds is depth: you get a well-rounded view of the candidate’s skills, personality, and culture fit over time. The risk? Too many rounds can frustrate candidates and drag out the process, especially if there’s overlap or disorganization.
When to use it:
- Mid-level to executive roles
- Complex hiring decisions requiring input from multiple departments
- Roles where both technical skills and leadership qualities need evaluation
Pros:
- Allows for thorough evaluation of hard and soft skills
- Enables diverse stakeholders to weigh in
- Builds buy-in from team members and managers before the offer is made
Cons:
- Can extend time-to-hire if not managed efficiently
- Risks candidate dropout if communication or scheduling is poor
- Can become repetitive or redundant without clear structure
How to Choose the Right Interview Format
Choosing the right interview format isn’t about following trends; it’s about aligning the process with the role, the team, and the candidate experience. Too often, companies default to what is familiar rather than what is effective. But when you match the format to the hire, you don’t just fill a seat, you make a great hire that lasts.
Here’s the framework I use with clients to find the right fit:
1. Define what you’re actually hiring for
- Are you hiring for skill, potential, or culture fit?
- Is this a hands-on role or a strategic/managerial one?
- Will they work independently or collaboratively?
Example: For a warehouse supervisor, a working interview or behavioral interview focused on conflict resolution may be more valuable than a traditional panel.

2. Match the format to the role
| Role Type | Recommended Format |
|---|---|
| Entry-Level / High-Volume | Phone Screen → Group or One-on-One |
| Technical / Skilled | Technical Interview → Panel or Working Interview |
| Managerial | Behavioral + Panel + Case Interview |
| Executive | Structured + One-on-One + Culture Fit Panel |
| Creative / Collaborative | Portfolio Review + Working Interview or Case |
3. Consider the candidate experience
A great interview process doesn’t just assess candidates, it impresses them. In today’s competitive market, top talent often has multiple offers. If your interview process is clunky, confusing, or overly drawn out, they’ll opt out quietly and quickly.
Questions to ask yourself:
- Is the process clear and well-communicated?
- Are there unnecessary or repetitive steps?
- Does each round add unique value to the evaluation?
Remember, the interview is often a candidate’s first, and possibly most lasting, impression of your company culture. If your team is disorganized or your questions feel disconnected, it can signal deeper issues.

4. Use tech to support, not replace, good judgment
AI and automation have revolutionized recruiting, but they’re not magic bullets. The best interview processes use tech as an enhancer, not a substitute for thoughtful human evaluation.
Use tech to:
- Pre-screen candidates with skills assessments or resume parsing
- Automate interview scheduling and reminders
- Standardize scoring with structured question templates
- Analyze trends in interview feedback and time-to-hire data
However, don’t fall into the trap of letting automation replace genuine connection, especially in roles where emotional intelligence, leadership, or communication are essential.
5. Pilot, measure, improve
One of the biggest mistakes hiring teams make is setting an interview process… and never revisiting it. The hiring landscape changes fast. What worked two years ago may be costing you candidates today.
How to keep your interview formats sharp:
- Track performance data post-hire (retention, ramp-up time, manager feedback)
- Survey candidates on their experience (even those you don’t hire)
- Review rejection points—where are good candidates dropping off?
Run small experiments. Try switching one panel round to a case study. Replace a phone screen with a text-based assessment. Add structure to an unstructured interview and see if scoring alignment improves.
