The CV box is the easy part. Below it, plenty of application forms add a row of extra upload slots labelled transcript, certificates, writing sample or simply "other documents", and those slots run on their own rules. Most of the late-stage friction in an application comes from them, not from the CV.
What the extra slots are really asking for
Every upload slot is a request from a specific person further down the process. The transcript slot is usually there for a graduate scheme or a regulated role, where someone has to check a grade or a degree class. The certificate slot is for a licence or language level the ad names, and the writing sample slot is for a hiring manager who wants to see you think on paper.
Read the label and the helper text under it before you upload anything. "Optional" on a form often means "optional for the software, expected by the reviewer", especially when the job ad itself mentions the document. If the ad asks for something and the form offers a slot, fill the slot. If neither mentions it, leave the slot empty rather than padding it with paperwork nobody requested.
The CV has its own questions (format, file type, and why the form fields repeat it), and other posts on this blog cover those. This one is about everything else you attach.
One slot, one file: merging into a single PDF
The most common surprise is a slot that accepts one file when you have four. Two degree certificates, a transcript and a language certificate, and the form gives you a single box called "Qualifications". Uploading the second file usually replaces the first, sometimes without a warning.
The fix is to merge them into one PDF before you open the form. Most operating systems can export several documents into a single PDF. Do it on your own machine rather than on a random website, since these files carry your name, your date of birth and sometimes an ID reference.
A sensible order inside the merged file
A reviewer opening a merged file reads the first page and then decides whether to scroll. Put the most useful document on top:
- The qualification the job ad names, highest level first.
- The transcript for that qualification, if the ad asks for it.
- Translations, placed directly after the original they translate.
- Older or secondary certificates at the end.
Once the file runs past five or six pages, add a one-line contents page: "MSc certificate (p.2), MSc transcript (p.3-4), sworn translation (p.5-6)".
Naming the files
Name every supporting file the way you would name the CV: your name, the document, nothing cryptic. "Lena-Ortiz-MSc-certificate-and-transcript.pdf" beats "scan0043.pdf" every time, because the file often gets downloaded and forwarded outside the system. Skip spaces and accented letters in file names; some systems mangle them.
Size caps and how to get under them
Many forms cap uploads at a few megabytes per file, and the cap is often stated only in grey text under the button, or not at all until the upload fails.
Ways to get under the cap without making the document unreadable:
- Scan at 150 to 200 dpi rather than 600. A certificate does not need print resolution.
- Use greyscale for text-only documents and keep colour for a seal or stamp that matters.
- Export the merged PDF with a "reduced size" option, then open it and check that small print and signatures are still legible.
- Crop the margins, and the kitchen table, out of phone photos before merging.
If the merged file still exceeds the limit, split it by priority rather than by page count: the key qualification goes in the slot, and a sentence in the free-text field says the full set is available on request.
Transcripts, certificates and translated diplomas
The transcript trips people up most, because universities issue several versions of it. An unofficial download from your student portal is usually fine at application stage; the official sealed copy tends to come later, at offer or onboarding, if anyone asks for it at all. When in doubt, upload the portal version and say so in the file name ("unofficial-transcript").
A diploma in another language needs a translation the reviewer can read. For many private employers, a clear personal translation placed right after the original is enough at screening. Public bodies, regulated professions and some universities want a sworn or certified translation instead, done by an accredited translator whose stamp carries legal weight in that country. The rules differ by country and by employer, so check the ad or ask the contact before paying for one. Sworn translations cost real money and take days, so I would order one only once the employer confirms it needs it, unless you are applying to several public-sector roles in the same month.
For degrees earned abroad, some employers also ask for a statement of comparability with the local system. If you hold one, it goes straight after the diploma and its translation.
Writing samples and portfolios as files
A writing sample slot is a small audition. Pick a piece close to the job: a policy brief for a policy role, a report extract for an analyst role, release notes for a technical writer. Two to five pages beats a forty-page thesis. If your best piece is long, export the relevant section and add a short header saying where it comes from and which parts you wrote.
Check confidentiality before you upload. Client work, internal reports and anything published under an employer's name may not be yours to share; anonymise it or pick something else. A sample that leaks a former employer's data tells the reviewer more about you than the prose does.
Portfolios are trickier, because the slot wants a file and your work lives online. Build a short PDF of six to ten pieces, one per page, each with a line of context. Compress the images, or the size cap will reject the file.
What reviewers actually open, and when
At the first screen, a reviewer typically opens the CV and perhaps the cover letter. Supporting documents get opened when the CV raises a question they can settle: does this person hold the licence, what grade did they get, can they write. They also get opened later, often by someone else, when HR checks qualifications at shortlist or offer stage.
That has two consequences. The first page of every file should answer the obvious question on its own. And each file has to make sense to someone who never read your CV, which is one more reason for clear names and a contents line.
If you build your CV from your LinkedIn profile with a tool like Postulit, keep the qualification names and dates in that CV identical to the documents you upload. A reviewer who sees 2021 on the CV and 2022 on the certificate will stop and ask.
What not to upload before an offer
Some forms include a slot for identity documents, proof of address or right-to-work papers at the very first application. Treat that slot as a question, not an instruction.
Do not upload a copy of your passport or ID card, an ID or social security number, or bank details until you have verified the employer and you are at offer or onboarding stage.
Legitimate employers check right to work and collect payroll details after the offer, through their own onboarding. Before that point, a yes-or-no answer to "do you have the right to work in this country?" is enough. Requests for ID and bank details on a first application are a classic feature of job scams, which have their own guide on this blog.
If the slot is mandatory and demands ID, upload a short note saying the document is available at offer stage, or contact the recruiter to confirm what they actually need.
Before you click submit
Open the form first and list every upload slot with its size cap. Then build your files to match: one merged PDF per slot in a sensible order, named with your name and the document, compressed but legible, with each translation right after its original. Keep these files in one folder, and the next application takes ten minutes instead of an evening.
