You have 30 minutes with a promising candidate, but their résumé already covers their experience. What should you ask to discover how they actually think, work, communicate, and solve problems? The best questions to ask while interviewing candidates do more than keep the conversation moving. They produce specific evidence that helps you compare applicants fairly and predict how each person may perform in the role.
Effective interviews focus on job-related behavior rather than charm, rehearsed answers, or personal similarities. Ask every candidate the same core questions, use follow-up prompts when necessary, and evaluate answers against clear criteria established before the interviews begin.
What Makes an Interview Question Effective?
A strong question is open-ended, relevant to the position, and difficult to answer with a simple yes or no. It should invite the candidate to describe a real example, explain a decision, or work through a realistic situation.
Before asking a question, consider what you are trying to measure. Is it communication, judgment, technical knowledge, reliability, leadership, or adaptability? If you cannot connect the question to an important job requirement, it may not belong in the interview.
Best Questions to Ask While Interviewing Candidates
1. “Tell me about a project or accomplishment that best demonstrates your ability to succeed in this role.”
This opening question gives candidates room to select relevant evidence from their experience. It also reveals whether they understand the position and can connect their background to its requirements.
Listen for a clear explanation of the objective, the candidate’s individual contribution, the challenges involved, and the result. If the answer stays vague, ask, “What part did you personally handle?” or “How did you measure success?”
2. “Describe a difficult problem you faced at work. How did you approach it?”
Problem-solving questions reveal more when they focus on the process rather than whether the story ended perfectly. A valuable answer explains how the candidate gathered information, considered alternatives, involved other people, and chose a course of action.
Pay attention to whether the person identifies the root problem or immediately jumps to a solution. Strong candidates can usually explain both what they did and why they did it.
3. “Tell me about a time you made a mistake. What happened next?”
This question assesses accountability, self-awareness, and learning. Everyone makes mistakes, so claiming otherwise may suggest limited reflection or reluctance to accept responsibility.
A constructive answer acknowledges the candidate’s role without excessive blame, describes how the issue was corrected, and identifies a lesson or process change. The seriousness of the mistake matters less than the judgment and growth demonstrated afterward.
4. “How do you decide what to work on first when several tasks are urgent?”
Instead of asking whether someone is good at time management, this question explores how they prioritize in practice. Candidates may discuss deadlines, business impact, dependencies, customer needs, or conversations with managers.
Look for a repeatable method rather than broad claims about working hard. An effective employee should also recognize when competing priorities require clarification instead of trying to handle everything silently.
5. “Tell me about a time you received feedback that was difficult to hear.”
This is one of the best questions to ask while interviewing for roles that require collaboration and continuous learning. It shows how a candidate responds when their performance or approach is challenged.
A strong response demonstrates emotional control, curiosity, and willingness to improve. Be cautious about answers that dismiss the feedback, portray every critic as unreasonable, or fail to identify any resulting change.
6. “Describe a disagreement with a coworker or manager. How did you handle it?”
Healthy workplaces do not eliminate disagreement; they manage it productively. This question can reveal communication style, empathy, professionalism, and the ability to separate ideas from personalities.
Listen for evidence that the candidate sought to understand the other person, communicated directly, and worked toward an appropriate resolution. The goal is not to find someone who always gives in, but someone who can disagree without damaging working relationships.
7. “Imagine you joined us and encountered this situation. What would you do first?”
A job-related scenario helps evaluate how candidates apply their knowledge to realistic challenges. Describe the situation clearly, provide the same information to every applicant, and avoid creating a puzzle with one hidden “correct” answer.
Good responses may begin with questions. That is often a positive sign because workplace decisions usually depend on context. Evaluate the assumptions candidates make, the risks they notice, and how logically they explain their next steps.
8. “What conditions help you do your best work?”
This question can uncover practical preferences related to communication, independence, feedback, planning, and collaboration. It may also help you identify a mismatch between the candidate’s needs and the role’s actual environment.
Do not treat one work style as universally superior. Instead, determine whether the candidate can perform effectively under the conditions the job genuinely requires.
9. “Why are you interested in this position, and what would you like to learn here?”
This question explores motivation without expecting exaggerated enthusiasm. A thoughtful response should show that the applicant understands the opportunity and has considered how it fits their experience or goals.
Answers may also reveal which parts of the position require further explanation. Interest alone does not establish ability, but motivation can help distinguish between candidates with otherwise similar qualifications.
10. “What questions do you have for us?”
Leave enough time for a meaningful answer. Candidate questions can indicate preparation and priorities, but avoid judging someone solely by how many questions they ask. Important topics may already have been covered, and some applicants may be nervous.
Interviewers should respond honestly and allow candidates to evaluate the opportunity too. For another perspective, see these essential questions candidates can ask at the end of an interview.
Follow-Up Prompts That Produce Better Answers
Even a well-designed question may initially produce a general response. Neutral follow-up prompts help candidates provide useful detail without suggesting the answer you want.
- “What was your specific responsibility?”
- “What options did you consider?”
- “What was the outcome?”
- “How did you measure the result?”
- “What would you do differently now?”
Give candidates time to think. A brief pause often leads to a more accurate, thoughtful answer than immediately rephrasing the question.
Questions Interviewers Should Avoid
Keep questions connected to qualifications and essential job duties. Avoid inquiries about age, religion, disability, medical history, pregnancy, marital status, family plans, national origin, or other protected personal information. The U.S. Equal Employment Opportunity Commission explains that pre-employment information should generally be limited to what is necessary to determine whether an applicant is qualified; employers can review its guidance on prohibited employment policies and practices.
Rather than asking about health conditions or family responsibilities, state the position’s requirements and ask whether the candidate can meet them. For example, ask whether the person can work the published schedule or perform a specific essential job function, with reasonable accommodation where applicable. Because employment requirements may vary by jurisdiction, organizations should have their interview procedures reviewed by qualified human resources or legal professionals.
How to Compare Answers Fairly
Create a simple scoring guide before interviewing anyone. List the competencies being assessed and describe what weak, acceptable, and strong evidence would look like. Take notes about job-related examples rather than impressions such as “good energy” or “not a culture fit.”
After each interview, score the responses before discussing the applicant with other interviewers. This reduces the chance that one person’s opinion will shape everyone else’s memory. The final decision should reflect the complete evidence: relevant skills, demonstrated behavior, work samples when appropriate, and the candidate’s ability to meet the role’s requirements.
The best interview is not the one that feels most conversational. It is the one that gives every candidate a fair opportunity to provide meaningful evidence. By asking consistent, job-focused questions and listening for specific actions and results, employers can make more informed hiring decisions while creating a respectful candidate experience.
