The three words are used loosely, and job advertisements often ask for a CV when they mean a resume. What matters is matching the document to the reader.
Below is what each one contains, how long it should run, and how to tell which is being asked for.
Which document, and what it holds
-
01
Resume
One to two pages. Summary, experience with results, education, skills. Used by companies, startups and every job portal.
-
02
Academic CV
Two pages upward. Research interests, education with thesis titles, research and teaching experience, publications, awards, referees.
-
03
Biodata
One to two pages. Personal particulars, qualifications with marks, experience, declaration. Public-sector and administrative applications.
How to tell which one is wanted
Read the source of the request. A company careers page or portal that asks for a CV almost always means a resume, and a two-page document with a publication list will work against you there.
A university, funding body or research institute means an academic CV. A government notification that lists fields to fill in means a biodata in the format the notification prescribes.
Length, honestly
One page until roughly eight years of experience, two after that. An academic CV has no upper bound but should still be ordered so the first page carries the strongest evidence.
What every version shares
- Reverse-chronological order inside each section.
- Consistent dates and consistent result formats.
- Achievements rather than duty lists.
- Contact details that work, checked before sending.
- A file name with your own name in it.
Frequent mismatches
- Sending a six-page academic CV to a company recruiter.
- Sending a one-page marketing-style resume for a PhD application.
- Personal particulars on a private-sector resume that never asked for them.
- A publication list with inconsistent citation styles.
Questions people ask
Is a CV the same as a resume?
Not exactly. In common use they overlap, but a CV is the longer academic record and a resume is the short, targeted document companies read. Match the document to who is reading it.
Can I use one document for every application?
Keep one base and adjust the emphasis. The section order should change between an academic application and a company one.
Should a job CV include references?
Only if asked. Otherwise leave the space for evidence and supply referees when the employer requests them.
