Interview availability request email: asking before you offer times

An interview availability request email asks the candidate — or, on the internal side, the interviewer — when they're free, before anyone commits to a specific time. This is the step that comes before an invitation, not a substitute for one: once you have real availability from both sides, you send the actual invitation with a confirmed time attached. Skipping this step and guessing at times wastes more back-and-forth than it saves.

This differs from the invitation itself, covered in our interview invitation email template, which assumes you already know when to offer. Use an availability request instead whenever more than one calendar needs to line up, or when you genuinely don't know the candidate's constraints yet.

Hi [Candidate name],

[Client] would like to move forward with an interview for [Role]. Before
I go back and forth with their team, could you share a few windows over
the next [timeframe] that work for you?

It'll be [format], about [X] minutes, with [interviewer name/title if
known]. If you can give me 3–4 options across two or three different
days, plus your time zone, I can usually lock something in within a day.

Thanks,

Hi [Candidate name],

We'd like to schedule your interview for [Role] — [format], about [X]
minutes, with [interviewer name/title].

Could you share a few times over the next [timeframe] that work for you,
across a couple of different days if possible? Include your time zone if
you're not local to [company location/time zone] so I don't misjudge it.

Once I have your availability I'll confirm with [our team/the panel] and
send you a locked-in time within a day or two.

Internal: asking the interviewer or panel for their availability

Subject: Availability needed: [Candidate name] interview for [Role]

Hi [Interviewer name(s)],

[Candidate name] is ready to move forward for [Role]. Could you send me
a couple of windows over the next [timeframe] when you're free for a
[X]-minute interview?

If you're part of a panel with [other names], flag any days that are
definitely out so I can find the overlap faster.

Thanks,

A filled example

Notice this asks for exactly four things — timeframe, format, duration, and a spread across multiple days — in two short sentences. That's enough structure for a useful reply without turning the request itself into a form the candidate has to fill out.

Matching several people's availability without an endless thread

Asking each side separately, then matching manually, works for two people but breaks down past three. For a panel, a shared scheduling tool that shows overlapping free time removes a full round of email; where that isn't available, ask each interviewer for their available windows across the same set of days rather than open-ended "let me know when you're free," which produces answers too varied to match against each other efficiently. Set a deadline for replies, such as end of day on a specific date, so the process doesn't stall on the one person who hasn't answered yet.

Asking both sides at once, when the loop is simple

For a straightforward one-interviewer loop, it's often faster to ask both sides in parallel rather than sequentially: send the candidate's availability request the same day you ask the interviewer, instead of waiting for one reply before starting the other. This costs nothing extra and can cut a full day off the scheduling cycle, since you aren't waiting on two response times stacked one after another. The trade-off is that you may need to go back to whichever side gave narrower availability if the two windows don't overlap, so ask both for more options than you think you'll need rather than the bare minimum.

Following up when nobody replies

If a candidate hasn't replied within two to three business days, a short follow-up works better than resending the same message word for word: acknowledge the ask again briefly and offer to work around a tighter window if the original timeframe no longer fits. This does double duty — it also surfaces early whether a candidate has cooled on the process, rather than discovering that only after several rounds of scheduling back-and-forth have already gone nowhere.

What to do with vague or narrow availability

Two common replies need a follow-up rather than a guess: a candidate who gives only one option, and a candidate who says something too vague to schedule against, like "I'm pretty flexible." For a single option, ask for one or two backups in case it doesn't line up on your side — don't build a whole schedule around a single window with no fallback. For vague availability, ask a direct follow-up rather than proposing a random time and hoping: "could you give me a couple of specific windows over the next few days, even rough ones? That'll help me match you with the team faster."

Confirming time zone, every time

Ask for the candidate's time zone explicitly in the same message, rather than inferring it from their location or resume. A candidate who lists a city on their resume may currently be traveling, working remotely from a different region, or simply have moved since the resume was last updated. Once you have their stated availability and time zone together, convert everything to a single time zone before matching it against interviewer calendars — mixing "3pm their time" with "2pm our time" across an email thread is where scheduling errors usually start.

The common mistake

The most common mistake is asking an open-ended question — "when are you free?" — with no timeframe, no duration, and no format attached, which forces the candidate to guess what you actually need from them. A vague request gets a vague answer, and a vague answer starts another round of email instead of ending the back-and-forth. Always attach the specifics — timeframe, duration, format — to the availability request itself, so one reply from the candidate is enough to move straight to a confirmed invitation.

A related version of the same mistake is asking for availability from a candidate whose interest you have not actually confirmed yet. If a candidate has not responded to your last message in over a week, or their enthusiasm in the previous conversation was lukewarm, an availability request assumes an eagerness that may not be there, and a non-response then reads as a scheduling failure when it is really a re-engagement problem. Where interest is uncertain, a short check that they are still interested in moving forward gets a clearer answer than an availability request that quietly goes unanswered for the same underlying reason.
