Common Employment History Mistakes
Mistake 1: Date Discrepancies
Problem: Dates don't match tax records or LinkedIn Impact: Investigators will find discrepancies Solution: Cross-reference W-2s, tax returns, LinkedIn before submitting
Mistake 2: Gaps in Timeline
Problem: Unaccounted time between positions Impact: Investigation delay, additional questions Solution: Account for every month - even 2-week gaps need explanation
Mistake 3: Missing Short-Term Jobs
Problem: Omitting jobs held briefly Impact: Discovered during investigation, raises honesty concerns Solution: Include ALL employment, even jobs lasting weeks
Mistake 4: Wrong Supervisor Information
Problem: Supervisor no longer at company or wrong contact Impact: Delays as investigator tracks down correct person Solution: Research current contact info, note if supervisor left company
Mistake 5: Vague Reasons for Leaving
Problem: Generic explanations like "personal reasons" Impact: Raises red flags, requires follow-up Solution: Be specific but professional ("accepted position with higher salary")
Handling Difficult Employment Situations
Terminated for Cause
| Situation | How to Handle |
|---|---|
| Fired for performance | State factually, don't be defensive |
| Fired for misconduct | Disclose honestly, explain lessons learned |

Example disclosure for termination:
"Terminated due to policy violation regarding [brief description]. Have since completed [relevant training/changed behavior]. No similar issues in subsequent employment."
Company No Longer Exists

|---|---|
| Company closed | Note "Company no longer in business" |
| Company acquired | List original name, note acquisition |
| Records unavailable | Provide best information, note limitation |
Verification alternatives:
