A shortlist answers two questions: who fits the role, and who can actually start when the role needs to be filled. The second question is often left until the offer, when it is too late to change course. Your Applicant Tracking System should record, for every candidate before they move to the shortlist stage, the notice period as the candidate stated it, the earliest realistic start date that follows from it, and the date and person that confirmed it. With those fields filled, the client or hiring manager compares candidates on the same basis, and nobody discovers at the offer stage that the preferred candidate cannot start for another three months.
The reasons differ per segment. Recruitment agencies present candidates against a start date that the client often agreed with its own business. Staffing desks work with short lead times, where a week of notice can decide whether a candidate is placed at all. Secondment teams need to know when a professional is free from a current assignment or employer before promising a new one. Executive search firms deal with long notice periods and negotiated release dates for senior candidates. In-house recruitment teams have to align the start date with budgets, onboarding and the team that is waiting.
Why missing notice periods break shortlists
The same patterns appear on many desks:
- The notice period was mentioned in the first call, but it sits in a personal note or an email instead of in the candidate record
- Two candidates on the same shortlist look equal, but one can start next month and the other in a quarter, and the client only hears this after choosing
- The recruiter assumes a standard notice period instead of asking, and the actual employment contract says something else
- A process takes longer than planned, and the earliest start date that was right at the first interview is no longer right at the offer
- The vacancy has a target fill date, but nobody checks whether the shortlisted candidates can meet it
None of this needs a new tool. It needs a few recorded facts at the right moment in the pipeline.
What to record before a candidate goes on the shortlist
- Notice period as stated — the length in weeks or months as the candidate gave it, and whether it ends on a fixed day such as the end of a calendar month
- Current situation — permanent employment, a fixed-term contract, freelance work, or a current secondment with its own end date; each situation leads to a different earliest start
- Earliest realistic start date — the date that follows from the notice period if the candidate resigned after an offer, written as a date rather than as a vague phrase
- Known constraints — planned leave, a project the candidate wants to finish, or a possible early release, recorded only as the candidate described them and never assumed
- Confirmed on and by whom — the date the information was asked and the recruiter who asked it, so a colleague can see how fresh it is
- Status — unknown, stated by the candidate, or reconfirmed later in the process
The Applicant Tracking System records what the candidate states. It does not interpret an employment contract or give legal advice; when the candidate is unsure, the right next step is to ask them to check their contract, not to guess.
Make it a condition of the shortlist stage
Configure the Applicant Tracking System so that a candidate can only move into the shortlist stage when the notice period and earliest start date are filled. The stage change then records who moved the candidate and when. When the information is missing, the move is blocked and the owner of the role receives a next-action date to ask for it. Compare each earliest start date with the target fill date and the required start in the structured brief: a candidate who cannot meet it can still be shortlisted, but the difference is visible on the shortlist instead of hidden in a note. Whether that difference matters remains a decision for the recruiter and the client.
Share the start date with the client in the right way
When you present a shortlisted candidate, include the earliest realistic start date in the submission, so the client compares candidates on availability as well as fit. Share only what the client needs: the date and any agreed constraint, not details about the current employer that the candidate did not agree to share. The submission itself still follows the usual rules: candidate consent first and a response deadline for the client. Record the start date the client actually requires on the client side, in the candidate and client relationship records beside the pipeline, so the next vacancy for the same client starts with a realistic expectation.
Keep it current until the start date
- Reconfirm the notice period and earliest start date when the candidate reaches the offer stage, and again if the process has taken longer than planned
- Put the earliest start date into the offer conversation, next to the acceptance deadline, so both dates are agreed together
- When the candidate resigns, record the resignation date, so the start date follows from facts rather than from the original estimate
- If the candidate mentions a counter-offer or a negotiated early release, record it as a stated fact with a date
- Close the loop with a confirmed start date before the vacancy closes
Report honestly on availability
Once the fields are filled, the Applicant Tracking System can show how many shortlisted candidates had a recorded notice period at the moment of submission, and how many offers moved because the start date did not match what the client expected. Measure the time from accepted offer to first working day separately from the time to fill, using the same definitions as in reliable time-to-fill reporting, because notice periods sit outside the control of the recruiter. Report the actual counts from your own records, show how many vacancies sit behind each figure, and do not quote general benchmarks for notice periods that you cannot verify.
Where artificial intelligence may help — and where it must not
Artificial intelligence may point out shortlisted candidates whose notice period is missing or older than an agreed number of weeks, calculate a first suggestion for the earliest start date from the notice period that was recorded, or draft a short question to the candidate asking them to confirm it. It must stay secondary. Artificial intelligence does not replace recruiters, does not fill in a notice period that the candidate never stated, does not interpret employment contracts, and does not remove a candidate from a shortlist because of availability. The Applicant Tracking System holds the stated facts; the owner of the vacancy decides.
A practical week to get started
- Add fields for notice period, current situation, earliest realistic start date and confirmation date to the candidate record
- Add the notice period question to the script for the first screening call
- Make the fields required for the move into the shortlist stage, and agree what happens when a candidate does not yet know the answer
- Go through the shortlists of open vacancies today and fill in the missing notice periods by asking the candidates, with the date of the answer
- Add the earliest start date to the format you use for client submissions
The first week will surface a few uncomfortable gaps. That is the point: they are cheaper to find at the shortlist than at the offer.
Know who can start before you present them
A shortlist is only as useful as the start dates behind it. Record the notice period, the current situation, the earliest realistic start date and when it was confirmed for every candidate before the shortlist stage, share it with the client, and keep it current until the first working day.
