What an ATS actually is
An Applicant Tracking System is the database a company receives applications into. It parses your CV into fields — name, roles, dates, skills — and lets a recruiter search and filter across every applicant.
It is worth being precise here, because the internet is full of scary claims about ATS software automatically binning most CVs. An ATS is a filing and search tool, not usually an automatic rejection machine. The realistic risk isn't that a robot deletes you — it's that a recruiter searches for the words in their own job ad, and your CV doesn't contain them, so you never surface in the results.
Why generic CVs stall
One CV sent to twenty jobs is written in your words. The recruiter is searching in theirs. If the ad says "stakeholder management" and your CV says "worked with lots of departments", a human would see the match instantly — a keyword search will not.
This is also why volume alone rarely works. Twenty untailored applications routinely produce fewer interviews than five carefully matched ones.
How to tailor without lying
Read the ad as a checklist
Pull out the job title, the must-have skills and the recurring words. That list is what the recruiter will search for.
Mirror their words — where they're true
If you have the skill, name it the way they name it. If you don't have it, leave it out. Matching a keyword you can't back up in an interview costs you more than it gains.
Reorder, don't inflate
Move the relevant experience up and give it more lines. Cut or shorten what the role doesn't ask for. Same truth, different emphasis.
Keep the format parseable
Single column, standard headings ("Experience", "Education", "Skills"), real text rather than text inside images, and a normal file format. Elaborate multi-column designs are the ones that get mangled.
Research the company, then write the letter
The CV gets you found; the cover letter and the interview get you hired. Two specific sentences about the company beat two paragraphs about yourself.
The honest catch
Tailoring works. It is also slow — reading the ad closely, researching the company, rewriting the CV and the letter for each role takes hours. That is the real reason most people send the generic version.
Hi Hiro exists for exactly that gap: it researches the company behind the ad, then writes a CV, cover letter and interview prep matched to that specific role — from your real experience, never invented.
