Interview Questions to Ask Supervisor Candidates

The questions

Open any question to see why it works.

1. 1

   Walk me through a normal shift you ran. What time did it start, and what was the first thing you did?

   A concrete shift is harder to fake than a philosophy. Listen for whether the first hour goes on people and coverage or on their own task list, because supervisors who never stop doing the job are the most common failure in this role.

2. 2

   How many people have reported directly to you, and for how long?

   Span of control changes the job more than industry does. Three people for six months is a different skill set from thirty for five years, and either can be right depending on the team you are filling.

3. 3

   Were you promoted from inside a team you then supervised?

   This is the most common route into a first supervisory role and the hardest one. Ask what changed in the first month with former peers, and whether any friendship did not survive it.

4. 4

   Tell me about a time you had to fill a shift at short notice.

   In shift environments coverage is most of the job. Good answers include the order they called people in, whether they ended up working it themselves, and what that cost them the following week.

5. 5

   What do you do when the same person keeps calling out?

   You are listening for whether attendance is treated as a documented pattern or as a series of separate irritations. Ask at what point they involved HR and what actually happened afterwards.

6. 6

   Describe the last difficult conversation you had with someone on your team.

   The word last matters, because it stops them selecting their best story. If they cannot recall one at all, they either avoid those conversations or have not supervised anyone recently.

7. 7

   How do you run a one to one, and how often?

   Answers range from a weekly fifteen minutes to nothing at all. Nothing is not disqualifying in a busy operation, but the candidate should be able to say how else they know what is going on.

8. 8

   Have you ever had to write someone up? Take me through the first one.

   Documentation is where inexperienced supervisors create problems for the employer. Listen for whether they recorded facts and dates or characterizations, and whether anyone reviewed it before it was issued.

9. 9

   Have you dismissed anyone? What did you do the day before, and the day after?

   The day before shows whether it was a process or a reaction. The day after shows whether they thought about the rest of the team, who all know within the hour and are watching how it was handled.

10. 10

    When did you last disagree with a decision from above and still have to deliver it?

    This is the load-bearing supervisory skill. The bad answer is announcing a decision while distancing themselves from it, which is extremely common and quietly corrosive to everything above them.

11. 11

    Tell me about someone you developed. Where are they now?

    Ask for a first name and a current role. Supervisors who genuinely develop people keep track of them; those who have learned the vocabulary of growth usually cannot finish this answer.

12. 12

    How do you decide who gets the good shifts, the overtime, or the easy assignment?

    Perceived unfairness in scheduling generates more grievances than pay does. Look for a stated method rather than a claim that everyone is treated the same, which is never true and never believed.

13. 13

    What would your team say you are strict about?

    Effective supervisors have two or three non-negotiables and can name them immediately. Hesitation usually means they enforce inconsistently, which their team worked out long before you did.

14. 14

    Tell me about a safety rule you had to enforce when it was inconvenient.

    The inconvenient case is the only one that tests anything. Note whether they stopped the work, who they told, and whether they reported something that made their own numbers look worse.

15. 15

    What do you do about two people who will not work together?

    Listen for whether they separate, mediate or escalate, and above all how long they let it run first. Interpersonal conflict is the thing supervisors most often postpone until it has become a formal complaint.

16. 16

    What have you been bad at as a supervisor?

    A real answer names a specific behavior and what they changed. Perfectionism and caring too much mean the question failed, so ask it again more narrowly: what did your last manager put on your review?

17. 17

    When has your team missed a target, and what did you say to them?

    You get two things at once: whether they own results or place them elsewhere, and their actual vocabulary in front of a team, which you can compare with how carefully they have spoken to you.

18. 18

    What would you do in your first two weeks here?

    Candidates who say they would learn the flow and listen are usually right for a frontline role. A complete change plan formed before seeing the place is a risk, so ask what would make them abandon it.

19. 19

    What would make you leave a supervisor job?

    More candid than asking why they left the last one. Answers about being left unsupported after an unpopular decision are worth exploring, because they tell you what backing this person will need from you.

20. 20

    What do you want to know about the team you would be taking over?

    Strong candidates ask about turnover, who applied for this job internally, and what the previous supervisor did badly. No questions at all is the clearest signal available in the whole interview.
