A job interview is a formal meeting in which an applicant is asked questions to determine their suitability for a particular job.
Job interviews come in all shapes (face-to-face, phone or video interview) and sizes (one-on-one, panel or group interview), but no matter what the format, every job interview can be structured in 3 different ways:
- Structured interviews
- Unstructured interviews
- Semi-structured interviews
What are the differences between these 3 types of job interviews?
Which one should you use to assess candidates?

Structured interview definition: What are structured interviews?
A structured interview is a type of interview in which the interviewer asks a particular set of predetermined questions.
In structured interviews, questions are planned and created in advance, which means that all candidates are asked the same questions in the same order.
Structured interviews are also known as:
- Standardized interviews
- Patterned interviews
- Planned interviews
- Formal interviews
Advantages and disadvantages of structured interviews
Advantages of structured interview
Since in structured interviews all the candidates are asked the same questions, it’s easy to compare their answers and hire the right job candidate. You can evaluate candidates in a most objective and fair way, which also makes structured interviews more legally defensible.
Disadvantages of structured interview
On the other hand, structured interviews are harder and more complicated to develop. You have to write them, test them and make sure interviewers stick to them.
You also risk your interview questions leaking out, which means future candidates can come prepared.
Finally, this type of one-size-fits-all interview can seem a bit cold and unpersonalized, making it harder to provide an excellent candidate experience.
How to conduct structured interviews
Keep your interviews structured in 5 simple steps:
1. Develop and write down interview questions to ask candidates.
2. Develop and write down a scale that will be used to grade candidates answers. (Need an example? Check out Google’s grading rubric for structured interviews.)
3. Print out your questions and bring them with you to the interview site.
4. Take detailed notes of each candidate’s answers.
5. Grade your candidates’ answers according to previously determined scale.
Unstructured interview definition: What are unstructured interviews?
An unstructured interview is a type of interview in which the interviewer asks questions which are not prepared in advance.
In unstructured interviews, questions arise spontaneously in a free-flowing conversation, which means that different candidates are asked different questions.
Unstructured interviews are also known as:
- Informal interviews
- Casual interviews
- Free-flowing interviews
Advantages and disadvantages of unstructured interviews
Advantages of unstructured interviews
The main advantage of an unstructured interview is their personalized approach. This is especially useful when you compare candidates who are equally qualified or for jobs where their personality and communication skills are crucial.
Additionally, since unstructured interviews allow for a free-flowing conversation, they seem much more casual and help candidates relax and feel more comfortable during the interview.
Disadvantages of unstructured interviews
Since in unstructured interviews different candidates are asked different questions, it’s harder to compare their answers and evaluate candidates equally and objectively.
How to conduct unstructured interviews?
Although unstructured interviews don’t use questions prepared in advance, that doesn’t mean that questions asked in unstructured interviews are totally random.
Here are the most important guidelines for conducting unstructured interviews:
1. Keep in mind interview’s purpose and the general experiences and qualities you are looking to asses in candidates. Your goal is to gather and record important information about candidates.
2. Make sure you have a focus, but be flexible to proceed based on the candidate’s responses.
3. You can start by asking "tell me about yourself" and then proceed by exploring specific interesting points from your candidate’s resume.
Semi-structured interview definition: What are semi-structured interviews?
A semi-structured interview is a type of interview in which the interviewer asks only a few predetermined questions while the rest of the questions are not planned in advance.
In semi-structured interviews, some questions are predetermined and asked all candidates, while others arise spontaneously in a free-flowing conversation.
Semi-structured interviews are also known as:
- Moderately structured interviews
- Hybrid interviews
- Combined interviews
Advantages and disadvantages of semi-structured interviews
Advantages of semi-structured interviews
Since semi-structured interviews combine both the structured and unstructured interview styles, they can offer the best form both worlds.
They can secure objective comparison of candidates, but at the same time provide a more personalized and spontaneous approach that allows exploration of interesting points in specific candidate’s resume.
Disadvantages of unstructured interviews
Compared with structured interviews, semi-structured interviews are less objective and legally harder to defend.
How to conduct semi-structured interviews?
Here are the most important guidelines for conducting semi-structured interviews:
1. Write down most important questions that you want to ask all the candidates.
2. Develop a few conversation starters to explore specific interesting points from your candidate’s resume.
3. Depending on your candidates' answers, ask follow up questions to gain a more in-depth understanding of their qualifications and motivation.
4. Follow the natural flow of conversation and feel free to explore any new job-related topic that arises spontaneously.
Conclusion: Which type of job interview should you use?
Recruiters and human resources professionals divide job interviews into 3 different types: structured, semi-structured and unstructured interviews.
A structured interview is a type of interview in which the interviewer asks a particular set of predetermined questions, while the unstructured interview is a type of interview in which the interviewer asks questions which are not prepared in advance. A semi-structured interview is a hybrid of the previous two types, which means that some questions are predetermined, while others arise spontaneously in a free-flowing conversation.
