Pharmacist Interview Questions

I was drawn to pharmacy because it sits at the intersection of science and direct patient care. I wanted a clinical role where I could apply deep pharmacological knowledge while having real conversations with patients at one of the most important moments in their healthcare journey. What keeps me motivated is the variety: no two days are the same, and the decisions we make genuinely affect patient outcomes. I find particular satisfaction in medication reviews where I identify an issue the prescriber had not considered, or in counselling sessions where a patient leaves understanding their treatment for the first time. Staying current with NICE guidance, BNF updates, and GPhC continuing development requirements also keeps the work intellectually engaging. Pharmacy is not a passive role, and that suits me well.

I make regular CPD a non-negotiable part of my working week rather than something I fit in around busy periods. I use a mix of resources: NICE clinical guidelines, MHRA safety alerts, BNF updates, and the GPhC revalidation framework all feed into my structured learning plan. I also attend sector study days when possible and discuss clinical queries with colleagues because peer learning often surfaces practical insights that written guidance does not. When new drugs are added to the NHS formulary, I do a structured review of the prescribing information and any comparative studies before I start dispensing them. After any CPD activity I write a brief reflective note on how I will apply the learning, which helps retention and keeps my revalidation portfolio current.

I approach these relationships as a genuine clinical partnership. Pharmacists and prescribers have overlapping but distinct knowledge bases, and the best patient outcomes come from both perspectives being used. In practice this means I am proactive about raising concerns or queries rather than waiting to be asked. If I spot a potential drug interaction or an unusual dose, I contact the prescriber promptly, frame the question professionally, and document the outcome. I also make myself available for informal clinical conversations because good relationships with GP surgeries or ward teams make those calls much easier when something urgent comes up. I have found that prescribers who initially seem resistant to queries become more receptive once they see that the goal is always patient safety.

During a busy afternoon shift I picked up a prescription for metformin 500mg twice daily and noticed the label had been printed for metformin 5000mg. The label had passed the initial accuracy check. I stopped the dispensing immediately, quarantined the item, and reported the near-miss through our incident reporting system before the end of shift. I then spoke with the pharmacy team to understand how the decimal error had occurred: it turned out a data entry field had auto-populated incorrectly from a previous prescription. I wrote up the incident and suggested we add a mandatory dose-range alert for metformin in the dispensing software. The change was implemented within two weeks. The key lesson was that a near-miss is only useful if it changes the system, not just the individual behaviour.

A patient came to the counter visibly upset because their GP had not sent through a repeat prescription they needed urgently. They were on a critical medication and had only one tablet left. The patient became quite agitated and raised their voice. I stepped out from behind the counter, introduced myself, and asked them to come to the consultation room so we could talk properly. I listened without interrupting, then explained the options clearly: I could contact the GP surgery directly, issue an emergency supply under my professional discretion, or both. I reached the surgery, confirmed the prescription was being sent, and issued a short emergency supply to cover the gap. The patient left calm and with their medication. Giving them a quiet space and a concrete plan resolved the situation quickly.

A prescriber issued a prescription for a patient on warfarin that included a course of clarithromycin without any note about INR monitoring. The interaction is well documented and can significantly increase bleeding risk. I called the prescriber, introduced myself, and said I had a clinical query rather than framing it as a dispute. I explained the interaction, noted that the patient's last INR reading in our records was already at the upper end of the therapeutic range, and asked whether they wanted to add a monitoring recommendation or consider an alternative antibiotic. The prescriber acknowledged the concern and amended the prescription to include a five-day INR check. The patient's INR was elevated at that check and the warfarin dose was adjusted. The outcome reinforced for me why speaking up early is always the right call, and it aligns with what the GPhC expects of us as professionals.

My approach has three layers. First, I review the full medication list before processing any new prescription, not just the item in front of me. Most dispensing software flags known interactions automatically, but I treat those alerts as a starting point, not a conclusion. I also cross-reference with the BNF Interactions appendix for anything clinically significant. Second, I classify the interaction by mechanism and severity: a pharmacokinetic interaction affecting CYP450 enzymes behaves differently from a pharmacodynamic interaction, and the clinical relevance depends on the patient's specific situation. Third, I consider the patient's context: their renal function, age, existing conditions, and any previous tolerability issues. If I identify a significant interaction, I contact the prescriber with a clear recommendation rather than a vague concern, and I document the outcome in the dispensing record.

Accuracy under pressure comes from process discipline, not from working faster. I follow the same checking sequence on a quiet Tuesday as I do during a Friday lunchtime rush: read the prescription, check the patient details, verify the drug, dose, formulation, and quantity, check for interactions, and confirm the label before it leaves the dispensing bench. I also use physical separation: anything that has not been fully checked stays on one side of the bench. I do not rely on memory for high-risk medicines such as anticoagulants, insulin, or opioids. I double-check these manually against the original prescription every time, regardless of how many times I have dispensed that drug for that patient. If the volume is genuinely too high for the current staffing level, I raise it with the pharmacy manager rather than compromise the checking process.

I start by finding out what the patient already knows and what their main concerns are. Patients retain information much better when it connects to something they already understand, and I avoid making assumptions about their health literacy. I cover four things in every counselling session: what the medicine is for, how and when to take it, the most important side effects to watch for, and what to do if something does not seem right. I use plain language and check understanding at the end by asking the patient to repeat back the key points in their own words rather than just asking "does that make sense?". For complex regimens or high-risk medicines like warfarin or lithium, I also provide written information to take away. I document every counselling session in the patient record, in line with GPhC practice standards.
