Intermediate Pharma QA Interview Questions
6. What is a deviation?
Sample Answer:
A deviation is any departure from approved procedures, specifications, or standards during manufacturing, testing, or packaging processes.
Types include:
- Planned deviation
- Unplanned deviation
QA investigates deviations to identify root causes and implement corrective actions.
7. What is CAPA?
Sample Answer:
CAPA stands for Corrective and Preventive Action.
- Corrective Action addresses existing problems
- Preventive Action prevents recurrence
CAPA helps improve quality systems and regulatory compliance.
8. What is change control?
Sample Answer:
Change control is a formal system used to evaluate, approve, document, and implement changes that may affect product quality.
Examples:
- Equipment modification
- SOP revision
- Process changes
- Facility changes
9. What is validation?
Sample Answer:
Validation is documented evidence proving that a process, method, or system consistently produces expected results.
Types include:
- Process validation
- Cleaning validation
- Method validation
- Equipment validation
- Computer system validation
10. What is out-of-specification (OOS)?
Sample Answer:
OOS refers to test results that fall outside predefined specifications or acceptance criteria.
QA investigates OOS results to determine:
- Laboratory errors
- Manufacturing issues
- Analytical problems

12. What is a batch manufacturing record (BMR)?
Sample Answer:
BMR is a documented record containing complete manufacturing details of a batch, including:
- Raw materials
- Processing steps
- Equipment used
- In-process checks
- Yield calculations
- Operator signatures
13. What is the difference between incident, deviation, and OOS?
Sample Answer:
| Term | Meaning |
|---|---|
| Incident | Any unexpected event |
| Deviation | Departure from approved procedure |
| OOS | Test result outside specification |
14. What is risk assessment in QA?
Sample Answer:
Risk assessment identifies and evaluates potential quality risks that may impact product safety or compliance.
Common tools:
- FMEA (Failure Mode and Effects Analysis)
- Fishbone Diagram
- HACCP
15. What are the responsibilities of a QA officer?
Sample Answer:
A QA officer typically handles:
- Document review
- Batch release
- Line clearance
- Deviation investigations
- SOP management
- CAPA tracking
- Audit support
- Compliance monitoring
