Second interview questions to ask candidates: 30 questions built on what round one left open

A second interview should test what the first one could not: depth on the hardest parts of the job, the candidate's own part in the results they described, judgment in realistic situations, how they would work with this team, and what would make them accept or decline. Choose five to seven questions from the gaps in the first-round scorecards instead of starting from a generic list, and use the same rating scale as round one so the evidence adds up.

Below are 30 questions in six groups, each with what to listen for and a follow-up probe, plus a planning grid, questions to avoid and a scoring example. The email that invites the candidate back is in the second interview invitation email page.

What should a second interview do that the first did not?

Situational questions earn their place here. In the meta-analysis by McDaniel, Whetzel, Schmidt and Maurer (1994), which covered 245 coefficients from 86,311 people, situational interviews showed higher validity than job-related interviews, and structured interviews higher validity than unstructured ones.

How do you choose which questions to ask?

Start from the round-one scorecards or handoff notes, not from this list. Each gap points to a type of question:

Core questions (5-7):  1.[ ] 2.[ ] 3.[ ] 4.[ ] 5.[ ] 6.[ ] 7.[ ]
Same core questions for every candidate in round 2: yes / no

Use the same core questions for every candidate in the round, and tailor only the follow-ups. If round one flagged different gaps for different candidates, add one tailored question at the end rather than rewriting the whole interview.

Questions that test depth on the work

1. "Walk me through the hardest [core task] you've done in the last year, step by step." Listen for: specifics, sequence, why each step. Probe: "What would you do differently now?"
2. "In round one you mentioned [project]. What was the main technical or practical trade-off, and how did you decide?" Listen for: options considered, criteria. Probe: "Who disagreed, and what did they want instead?"
3. "Here is a [report / brief / sample of our work]. What would you change first, and why?" Listen for: priorities over polish. Probe: "What would you need to know before changing it?"
4. "What does good look like in this role after six months, from what you've heard so far?" Listen for: whether they understood the job. Probe: "What would you measure?"
5. "Tell me about a time your first approach to [core task] failed." Listen for: diagnosis, not blame. Probe: "How did you find out it wasn't working?"
6. "Which part of this job would you find hardest in the first three months?" Listen for: honest, specific self-assessment. Probe: "How would you get up to speed?"

Questions that separate the candidate's part from the team's

7. "You said the team grew revenue by [X]. What part of that was yours alone?" Listen for: a shift from "we" to "I". Probe: "What would have happened without you?"
8. "Who else could tell me about this project, and what would they say you did?" Listen for: names and roles, consistent with the story. Probe: "What would they say you could have done better?"
9. "What decision on that project did you make that someone above you could have overruled?" Listen for: real authority versus participation.
10. "Tell me about something you owned that went wrong." Listen for: ownership without excuses. Probe: "What did you change afterwards?"
11. "What did you do on that project that wasn't in your job description?" Listen for: initiative with a reason. Probe: "Who asked you to?"

Questions that test judgment in realistic scenarios

Write these from real situations in your team, with the details changed. Same scenario for every candidate.

12. "It's your second week. A senior stakeholder asks you to drop your plan for an urgent request. What do you do?" Listen for: clarifying questions before action. Probe: "And if your manager is unreachable?"
13. "You find an error in work that has already gone to a client. What happens next?" Listen for: speed, honesty, ownership. Probe: "What do you say to the client, word for word?"
14. "Two of your priorities are both due Friday and you can only finish one." Listen for: criteria and communication. Probe: "Who do you tell, and when?"
15. "A teammate keeps missing handoffs that affect your work." Listen for: direct conversation before escalation. Probe: "What if it continues?"
16. "You're given a target you think is unrealistic." Listen for: data and a counter-proposal, not refusal or silent acceptance.

Questions about working with this team

17. "How do you like to receive feedback, and what's the most useful feedback you've had?" Probe: "What did you do with it?"
18. "Describe a colleague you worked well with who was very different from you." Listen for: specific adjustments they made.
19. "This team works [mostly remotely / in shifts / across time zones]. What has worked for you in a setup like that?" Listen for: concrete habits.
20. "Tell me about a disagreement with a peer that you resolved." Probe: "What did you give up?"
21. "What do you need from a manager to do your best work?" Listen for: self-knowledge; compare with how the hiring manager actually works.

Questions about motivation and the decision

22. "What have you learned about the role since round one that changed your view of it?" Listen for: whether they did their homework.
23. "What would make you say no to an offer from us?" Listen for: deal-breakers you can still address.
24. "Where else are you in process, and what's your timeline?" Listen for: urgency; plan your decision date around it.
25. "What are your pay expectations for this role?" Ask about expectations, not history; see salary expectation questions for wording and state rules.
26. "What would you want to have achieved here in a year?" Listen for: fit with what the role can offer.

Extra questions for managers and senior roles

27. "Tell me about someone you hired who didn't work out. What did you miss?"
28. "How have you handled an underperformer in the last two years?" Probe: "How long did it take you to act?"
29. "What's a decision you made that your team disagreed with?" Probe: "How did you tell them?"
30. "What would your first 90 days here look like?" Listen for: listening before changing things.

Which questions should you avoid in a second interview?

• Round one's questions again. The candidate gives the polished version and you learn nothing new.
• Personal topics that tend to come up as rapport grows: family plans, health, age, religion. See illegal interview questions.
• Unanchored "fit" questions such as "would I want a beer with you?" They score similarity, not the job.
• Hypotheticals with no right answer that nobody has written anchors for. If you cannot say what a good answer contains, do not ask it.

How do you score second-interview answers?

On the same scale and anchors as round one, so the scores combine. An example anchor for question 7 on a 1 to 4 scale:

More anchors are in the behavioral interview questions scoring rubric. Once round two is scored, the decision itself follows the rule in the hire or no-hire decision framework, and if a requirement is still untested, it gets one targeted follow-up, not a third full round; see how many interview rounds is normal.
