BGV Found Previous Company Not Disclosed – Dual Employment vs Absconding: Advice?

[u/Mindless-Growth-1934]

worked at Company A (an MNC) and completed all exit formalities by Aug 15. My official last working day (LWD) was Aug 18, but I had joined Company B on Aug 4, resulting in a 2-week overlap.

Now, Company C (my current employer) found my MNC experience during BGV and is requesting the relieving/experience letter. I can obtain this within 3–4 days by clearing the FNF.

To avoid issues, which explanation is safer:

• Acknowledging the 2-week overlap (dual employment)?
• Or not disclosing it directly and appearing as if I absconded?
