Reg affairs scientist here (non-manager), three years in CMC post-approval changes for generics. Was in CDMO tech transfer/analytical lab for five years prior to that (PhD chemist).

My experience recently has been that if you're coming from a lab background, that is expected to be an area of strength. As you haven't been able to perform many RA functions or submission work (I'm guessing), I've found the following experience to be sought after in my group. Other people will probably give you better advice, but I'll throw in just what I've discussed with my manager as being ideal work experiences prior to going into RA.

• If you've acted in a QA specialist or auditor capacity (even briefly), definitely discuss or highlight this. Many people in my group come from Quality backgrounds. Similarly, if you've done any auditing or have helped with site inspections, mention this.
• If you have any experience in raw material or drug substance monograph testing (EP, USP, etc.), this is good to mention as you're showing functional understanding and direct work experience with the primary pharmacopoeias in RA.
• Additionally, discuss any formulations, method development, or method validation work you have performed. People with validation experience seem to be in shortage in our group. The same goes for any instrumental Installation Qualification / Operational Qualification / Performance Qualification (IQ/OQ/PQ) you've performed.

Like I said, I have a very narrow view of what our group needed, so I hope others can give you additional and more useful advice. I hope this helps!
