Should you apply to old job postings? Usually not
Most job applications fail before a human ever sees them. If a role has been sitting on job platforms for days and the applicant count is already huge, you are usually walking into a process that already moved on without you.
Here is what most people do not think about. A role gets posted on LinkedIn or another one of the major job platforms. Within the first two or three days, the recruiter gets a wave of applications. They start reviewing job descriptions. They start shortlisting. They might even start reaching out for interviews.
And the job post? It stays up. For another week. Two weeks. Sometimes longer.
So when you come along on day twelve, see the role, think “that looks good,” and hit apply, you are submitting into a process that may already be past first review. The recruiter is not refreshing their inbox hoping for one more CV. They already have a shortlist. At that point, your application is usually just noise.
LinkedIn shows you this. It tells you when the role was posted. It tells you roughly how many people have applied. That information is not decoration. It is a signal. If a role is two weeks old and has 100+ applicants, it is probably one of the old job postings you should skip. A dedicated market activity tracker is really just a cleaner way of keeping those freshness and crowding signals visible.
I know it feels productive to fire off an application anyway. It usually is not.
Easy Apply is easy for everyone. That’s the problem.
I get the appeal. One click, done, move on to the next one. But if it is easy for you, it is easy for everyone. Which means the recruiter gets flooded with hundreds of applications, most of which are barely relevant.
You end up in a pile so large that no human is reading it properly. Filters do the work. Applicant tracking systems do the work. And unless your profile happens to be a near-perfect match on paper, you get filtered out before anyone even opens your CV.
That is why a generic CV is especially weak in crowded job posts. It rarely answers the specific role clearly enough. It usually repeats job titles, broad claims, and vague bullet points instead of surfacing relevant experiences, specific skills, and outcomes that are easy to read.
I am not saying never use Easy Apply. I am saying do not mistake low effort for efficiency. They are not the same thing.
Friction is actually your friend
This sounds backwards, but hear me out. Those job applications with the long, annoying forms? The ones that ask you to fill in your work history even though it is on your CV? The ones that want a cover letter, or answers to screening questions, or ask you to explain why you want the role?
They are filtering out your competition for you.
Most people hit that form, sigh, and close the tab. They go back to Easy Apply. They go back to the quick wins. Which means the people who actually complete those longer forms are a much smaller, more committed group. The recruiter sees fewer applications, spends more time on each one, and you actually have a chance of being read.
The friction is doing you a favour. It is just hard to see it when you are staring at a form asking you to manually enter your last five roles.
And those forms force a useful question: is this specific job actually worth the effort? Sometimes the best job listings are the ones with just enough friction to scare off the people spraying the same resume templates everywhere.
You do not need a new CV every time
People hear “tailoring” and imagine writing a new CV from scratch every time. That is the wrong model.
You do not need a new CV for every application. You need a tailored CV for the specific role: same truthful work history, same contact information, same core evidence, but reordered around the key skills, relevant experiences, and priorities that matter for that job.
That is also how you save time. If you keep a richer career record, you can generate a CV for a specific role much faster than if you keep copying from one stale document. Tailoring your resume should mean sharper selection and clearer wording, not inventing a shinier career.
If you are relying on a generic CV because you think volume is safer, you are usually just sending weaker job applications into harder pools.
How to actually do this
A few practical things that help:
-
Check the post date first. Before you even read the full job description, look at when the role was posted. If it is more than a week old and already has a high applicant count, think carefully about whether it is worth your time. Fresh job posts are where your effort pays off, and this is exactly the sort of timing signal a market activity tracker should keep in front of you.
-
Read the job description, not just the job title. A familiar title means nothing if the responsibilities, constraints, or specific skills are wrong for you.
-
Use alerts and a repeatable search process. Most job platforms let you create saved searches or alerts. If you want a more focused system than bouncing between stale tabs, use a sharper AI job search workflow to catch worthwhile roles earlier.
-
Do not shy away from longer application forms. Yes, they are tedious. But every field you fill in is another person who did not bother. That is the whole point.
-
Make the CV easy to read. Clear bullet points, accurate contact information, visible key skills, and honest work history give both recruiters and hiring managers less to decode.
-
Tailor every application that survives the filter. A generic CV submitted early is still weak. A tailored CV submitted early is where interviews are more likely to come from.
-
Track what you applied to. If you are being more selective, you should also be more organised. A job application tracker helps you remember which role you chose, what version you sent, and why you thought it was worth doing, while Search Insights should show whether those choices are improving response and interview rate.
Less noise, more signal
The job search is broken in a lot of ways, and most of the brokenness rewards volume over quality. But from the recruiter’s side, the experience is drowning in noise. If you can be one of the first, well-matched, clearly tailored applications they see, you stand out simply by not being part of the flood.
It feels counterintuitive to apply to fewer jobs. It feels like you are doing less. But you are not doing less. You are doing the thing that actually leads to interviews.
Old job postings, crowded job platforms, and a generic CV pull you toward busywork. A specific role, a tailored CV, and better timing pull you toward interviews.
Stop applying to dead jobs. Stop competing in the noisiest pools. Put your effort where it has a chance of being seen.
If you are unsure whether to apply to an old job posting, treat age and applicant volume as signals, not decoration.

Usually only if the role is specialised, the applicant count is still low, or the company has clearly reopened the search. Most old job postings posted on LinkedIn already have an active shortlist.
