What steps do you follow when receiving, storing or counting controlled substances?

What the interviewer is looking for

• This question tests pharmacy law & compliance. Follows controlled substance counting and record rules, patient privacy, and escalates discrepancies immediately.
• Strong answers: Verifies against the invoice, documents receipt, secure storage, accurate counts with a witness where required, and reports discrepancies.
• Likely follow-up: Which controlled substance records have you been responsible for keeping?

Another way it may be asked: A delivery of opioid pain medicine just arrived. What do you do from opening the tote to putting it away?

A structure to follow: Answer, explain, example, limits

1. Step 1

   Answer

   Give your direct answer in the first sentence so the interviewer knows where you are going.

2. Step 2

   Explain

   Say how it works or why you would do it that way, in plain words before jargon.

3. Step 3

   Example

   Anchor it in something you have actually done or seen, with the detail that shows hands-on experience.

4. Step 4

   Limits

   Say when your approach would not be the right one. It shows judgement.

This is guidance on shape, not a script. Use your own real experience and facts; never invent details to fill a gap. See the STAR guide and answer frameworks.

Common slips

• Reciting a definition without showing you have applied it.
• Using terms you cannot explain if asked a level deeper.
• Claiming experience beyond what you can discuss in detail.

How to practise it

Say the answer in 90 seconds, then answer the follow-up as if it were a new question.
