In India, three words get mixed up:
| Term | What it is in India | Use it for |
|---|---|---|
| Resume / CV | 1–2 page summary of skills, experience and education | Almost all private-sector jobs |
| Academic CV | Longer record of research, publications, teaching | Faculty, PhD and research roles |
| Biodata | Personal-details document: date of birth, father's name, religion, address, height, family | Marriage proposals; occasionally small local employers |
If a recruiter at a company asks for your "biodata", they almost always mean your CV. Send a proper CV, not a list of personal details. Government jobs are different again: they use their own application forms, so follow the form exactly and keep your CV for interviews or as an attachment.
The practical rule: one CV format for corporate jobs, tailored to each role, and official forms for government recruitment.
