# Candidate Import & Data Issues
## Resume Parsing Problems
### Parsing Failed
- **File format** — ensure the resume is PDF, DOC, or DOCX. Other formats are not supported.
- **File size** — resumes over 10MB may fail. Ask the candidate to compress the file.
- **Scanned documents** — scanned PDFs without text layers may have limited extraction. OCR quality varies.
- **Unusual formatting** — heavily designed resumes (infographics, multi-column layouts) may not parse correctly.
### Missing Data After Parsing
AI parsing extracts what it can find. If fields are missing:
- The information may not be present in the resume.
- The formatting may have made it undetectable.
- Manually add missing information to the candidate profile.
## Duplicate Candidates
### Automatic Detection
HireBee checks for duplicates based on email address when:
- A candidate applies to a job.
- You manually add a candidate.
- You import candidates in bulk.
### Merging Duplicates
If duplicates are found:
1. Go to **Candidates → Duplicates** (or you'll be prompted during import).
2. Review the duplicate pairs.
3. Choose the primary record to keep.
4. Click **Merge** — data from the secondary record is combined into the primary.
5. Applications, notes, and communications are preserved from both records.
## Bulk Import Issues
### Import Stuck or Failed
- Check the import job status in **Candidates → Import History**.
- Large imports (50+ files) may take several minutes.
- If an import fails, individual file errors are listed — fix and retry.
### Data Mapping
When importing CSV data:
- Column headers must match expected fields (name, email, phone, etc.).
- Email is the only required field.
- Unknown columns are ignored.
