Interview Panel Time Calculator
Interviewing Costs More Than the Time in the Room
Every interviewer pulled onto a panel is time taken away from their regular job, multiplied across every candidate and every round. It adds up quickly, and it's rarely visible until someone totals it — a small panel interviewing a handful of candidates can easily consume more collective staff time than the hiring manager expects.
The Formula
Total Interview Panel Time = Number of Interviewers × Interview Duration × Number of Candidates
Where This Is Useful
- Staffing impact — quantify the real opportunity cost of a multi-round, multi-interviewer hiring process before committing to it.
- Streamlining the process — compare total interviewer-hours across different panel sizes and round counts to see where trimming the process saves the most time without cutting rigor.
- Capacity planning — know in advance how much interviewer time a hiring surge (several open roles at once) will require from the team.
Worked Example
A 3-person panel, 45 minutes per interview, across 8 candidates:
| Interviewers | Duration per interview | Candidates | Total time |
|---|---|---|---|
| 3 | 45 min | 8 | 1,080 minutes (18.00 interviewer-hours) |
How to Use This Calculator
- Enter the Number of Interviewers on the panel.
- Enter the Interview Duration in minutes.
- Enter the Number of Candidates being interviewed.
- Select Calculate to get total interviewer-hours committed to this stage of the process.
