The Short Answer

Send one short message that does four things: names you, names the exact role, says where you got the number, and asks permission to send your CV. Then wait about a working week, send one follow-up, and stop. Three or four sentences is the right length, because a WhatsApp message that needs scrolling gets skim-read and answered later, which means never. Lead with your name, since HR does not know who an unknown number is, and name the role precisely ("the backend developer opening") rather than asking whether there are "any openings", which puts the work of guessing what you want on the person you are asking. Attach nothing until they say yes: an unexpected 2 MB PDF from a stranger is the fastest way to be ignored. And check the channel is appropriate first, because a number published for recruitment is an invitation, and a number you found in a group chat is not.

First, Is WhatsApp the Right Channel?

This decides whether a good message gets a good answer or no answer at all, and it is worth thirty seconds of thought. WhatsApp is appropriate when:

  • The company published the number for recruitment. A WhatsApp number in a job advert, on a careers page or in a hiring post is an invitation to use it.
  • HR or the recruiter messaged you first, or gave you the number in a conversation. Reply on the channel they chose.
  • Someone inside the company shared the contact and said to reach out. Say so in the first line, and name them.
  • It is how business is done in your market. In much of India, the Gulf, Nigeria and South Africa, WhatsApp is the normal channel for recruitment conversations, including with small employers who do not run an applicant tracking system at all.

WhatsApp is the wrong channel when the number is a personal one you obtained without permission, when the company has given you a careers portal and nothing else, or when you are applying to a large multinational whose process is entirely automated. In those cases the message does not just fail, it marks you as someone who ignored the stated process. Use email or LinkedIn, and keep WhatsApp for the stage where a human has already answered you.

One more rule that costs nothing: send during working hours in the recipient's time zone. A job enquiry that arrives at 11:40 PM is read in the morning anyway, and only tells them something about you that you did not intend to say.

The Five Things Every Message Needs

Almost every unanswered job message on WhatsApp is missing one of these, and the fix is mechanical:

  1. Your name, in the first line. HR sees an unknown number. Until you are a name, you are a possible wrong number.
  2. The exact role. "The QA engineer role posted on LinkedIn on Monday" is answerable. "Any vacancies?" requires them to interview you to find out what you want.
  3. Where the number came from. One clause: "your number was on the job post", "Rahul in the design team suggested I message you". This is the difference between an applicant and a stranger.
  4. One line of why you. Years, domain, and the single most relevant fact. Not a career summary.
  5. A clear, small ask. "May I send my CV here?" or "Is the role still open?" One question that can be answered with one word is what gets a reply the same day.

What to leave out: your full employment history, salary expectations, a photograph of your degree certificate, and anything that reads as pressure. Also leave out the attachment. Asking first takes one extra exchange and makes the second message welcome rather than intrusive.

Seven Scripts, by Situation

Replace anything in square brackets, and delete any line that is not true. All seven are deliberately short.

1. Cold introduction, number published for recruitment

Hello [HR name], my name is [Your name]. I saw this number on [Company]'s careers page for recruitment enquiries. I am a [role] with [X] years in [domain], most recently at [Company]. Are you currently hiring for [role / team]? Happy to send my CV here if that is useful.

The second sentence is the one people skip, and it is the one that stops the message reading like a mass forward.

2. A specific opening you found

Hi [HR name], I am [Your name]. I am writing about the [exact job title] opening at [Company], posted on [LinkedIn / Naukri / your site] on [day]. I have [X] years doing [the single most relevant thing], including [one concrete result]. May I send my CV for it?

This is the highest-reply-rate script here, because every question it raises is already answered. Quote the job title exactly as the advert words it, including a reference number if there is one, since HR may be running six searches at once.

3. With a referral from inside the company

Hello [HR name], [Referrer's name] in [their team] suggested I message you about the [job title] role. I am [Your name], [X] years in [domain]. [Referrer] and I worked together at [Company] on [project]. Would you like me to send my CV here, or apply through the portal?

Name the referrer in the first line, because that is the only part that changes how the message is read. Offering the portal as an option shows you are not trying to skip the process.

4. The one follow-up after applying and hearing nothing

Hi [HR name], [Your name] here. I applied for the [job title] role on [date] through [channel]. I know these take time, so no rush at all. I wanted to check it reached you, and whether there is anything else you need from my side.

Note what this does not do: it does not ask for a decision, which they may not have, and it does not imply they are late. It asks whether the application arrived and whether anything is missing, both of which are answerable in five seconds.

5. Asking permission before sending the CV

Thank you. Sending it now as a PDF, named [Firstname-Lastname-Role].pdf. In one line: [X] years in [domain], currently [role] at [Company], available from [date] and based in [city].

Send the summary in the chat and the file as the attachment. HR often triages on the phone, where opening a PDF is the expensive action, and a one-line summary in the message lets them decide before they open anything. Name the file properly: a CV called final-resume-2.pdf among fifty others is a document nobody can find again.

6. Reconnecting months after a previous conversation

Hello [HR name], [Your name] here. We spoke in [month] about the [role] at [Company], which went to someone else. Since then I have [one relevant change: shipped X, finished a certification, moved into Y]. If anything similar opens up, I would be glad to be considered. No reply needed unless something comes up.

The last sentence is what makes this message land rather than nag. You are giving them an item for a list, not asking them to do anything today.

7. Replying to "we will keep your CV on file"

Thank you, I appreciate you letting me know. Two things if you do not mind: is there a particular kind of role you would expect to come up for someone with my background, and would it be all right to check back in [three months]? Happy to send an updated CV then.

This turns a polite closure into a dated next step with permission attached, which is the only version of "keep in touch" that ever produces anything.

How Long to Wait, and How Many Times to Nudge

The question everyone gets wrong in both directions. Published recruiter guidance clusters tightly on one working week: StandOut CV's guide says you should not chase an application for at least one working week, because before that the recruiter most likely has not reviewed your CV yet, and Frontline Source Group's 2026 guide puts the window at roughly five to seven business days. Analyses of actual response times agree on the shape: Careery's 2026 write-up finds most interview-related replies land around the first week to ten days, which is exactly why a nudge on day two is noise and a nudge on day seven is useful. (StandOut CV's page is here; it would not load for us on October 6, 2026, so we are quoting the guidance as indexed rather than any figure beyond it.)

So, practically:

  • After applying: wait five to seven working days, then send script 4. Once.
  • After an interview: a thank-you the same day or the next, then wait for the date they gave you. If they gave none, one check-in a week after the interview.
  • After that: stop. One nudge per stage is the whole budget. A second changes nothing except how you are remembered, and in a small market you will meet this person again.
  • Silence after two messages is an answer. Spend the energy on the next application instead, which is the genuinely hard advice in this post.

The reason people break this rule is not impatience, it is memory. Day seven arrives while you are applying to four other things, and the nudge that would have worked gets sent on day nineteen, when it reads as desperate, or never.

Setting the Follow-Up the Day You Apply

The fix is to decide the follow-up date at the moment you apply, when you still care, and then get it out of your head. NagMeLater is a WhatsApp contact for exactly this: you text it a sentence, and it texts you back at the time you named. No app to install, and the first 7 days are free and unlimited.

Your first 7 days are free and unlimited

No app, no account. Save the number, send a message, done.

Two other commands matter once you have more than one application running. note Anita HR Acme, number from the LinkedIn post, applied Oct 6 for backend developer saves the context, and who is Anita brings back everything saved about her plus the reminder history, which is what you want open before you type the follow-up. And a to-do list with a tag, todo send CV to Acme #jobsearch, keeps the applications themselves separate from the follow-ups: project jobsearch then shows only that list.

If you would rather have the message itself ready to send, schedule message to 12024909133 on Monday at 10am: Hi Mehul, following up on my application for the backend developer role holds the text and hands you a one-tap link at the time, which opens that chat with the message filled in. You press send. We never send from your number and never read your chats, which also means the bot cannot tell whether HR has replied in the meantime; if they have, reply done to the reminder and skip it, or drop it from reminders with cancel 1 before it fires. The scheduled messages page covers the limits.

Five Mistakes That Cost Replies

Collected from the way these messages usually arrive:

  • Good morning sir, as a standalone message. Then nothing, waiting for permission to speak. It reads as a mass forward, and HR has to invest a reply before learning anything. Say everything in one message.
  • The unannounced attachment. A PDF from an unknown number is at best ignored and at worst reported. Ask, then send.
  • A voice note. It cannot be skimmed, searched or forwarded to a hiring manager, which are the three things your message needs to survive.
  • No role named. "Any openings for freshers?" is a question only a search engine can answer. Pick the specific role and say why you fit it.
  • Chasing more than once per stage. Three messages in a week converts a maybe into a no, and the person remembers the pattern long after they have forgotten your CV.

Once a reply lands and a conversation starts, the next thing you will need is a time, and that has its own etiquette. We wrote the templates for proposing, confirming and rescheduling one in how to ask for an interview time on WhatsApp.

Frequently Asked Questions

Is it unprofessional to message HR on WhatsApp about a job?

Not if the number was published for recruitment, the recruiter messaged you first, or someone inside the company gave you the contact and told you to use it. In many markets WhatsApp is the normal channel for hiring conversations. It becomes unprofessional when the number is a personal one you obtained without permission, or when the company has published a careers portal and you have gone around it. In those cases use email or LinkedIn.

What should the first WhatsApp message to HR say?

Four things in three or four sentences: your name, the exact role you are asking about, where you got the number, and one line on your relevant experience, ending with a single small question such as whether the role is still open or whether you may send your CV. Leave out your salary expectation, your full history, and any attachment until they have replied.

Should I send my CV straight away on WhatsApp?

No. Ask first, in the same message. An unexpected attachment from an unknown number is often ignored and sometimes reported as spam. Once they say yes, send a properly named PDF with a one-line summary in the chat text, because recruiters frequently triage on a phone where opening a file is the expensive step.

How long should I wait before following up with HR?

About a working week. StandOut CV's guidance says not to chase for at least one working week, since before that your CV has probably not been reviewed, and Frontline Source Group's 2026 guide puts it at five to seven business days. Response-time analyses such as Careery's 2026 write-up find most replies arrive in the first week to ten days, so a day-seven nudge is well timed and a day-two nudge is not.

How many times can I follow up?

Once per stage. One nudge after applying, one after an interview with no promised date, and then stop. Silence after two well-timed messages is itself an answer, and a third message mainly affects how you are remembered, which matters in any market where you will apply to the same employer again.

What time of day should I message HR?

Inside working hours in their time zone, ideally mid-morning on a weekday. A job enquiry that arrives late at night or on a Sunday is read on Monday regardless, and the timestamp is the only extra information it adds.

Can NagMeLater send the follow-up message to HR for me?

It can hold the text and hand it to you ready to send, but it cannot send it. WhatsApp does not let any app send from your personal number. At the time you chose, the bot messages you with the message and a link that opens that chat with the text already filled in, and you press send. It never reads your chats, so if HR has already replied, reply done to the reminder and skip it, or drop it from your reminders list before it fires.
