  • Attributable

  • Legible

  • Contemporaneous

  • Original

  • Accurate

These principles ensure that data is recorded responsibly and can be trusted during audits and inspections.

How to Answer:
Define each term clearly:

  • Attributable: Who performed the activity?

  • Legible: Can others read it clearly?

  • Contemporaneous: Was it recorded at the time of the activity?

  • Original: Is it the first or source record?

  • Accurate: Is the data correct and truthful?

Best Answer:
ALCOA+ expands the original ALCOA framework with additional attributes:

  • Complete

  • Consistent

  • Enduring

  • Available

These additions ensure the data is not only reliable but also maintained and accessible throughout its lifecycle.

How to Answer:
State that ALCOA+ reflects modern data handling requirements, especially for electronic systems.

Best Answer:
Yes, a common example is backdating entries in logbooks to cover up late documentation. Another example is overwriting electronic data without audit trail or deleting out-of-specification results to hide failures.

How to Answer:
Use real-world, simple examples and explain why it’s serious — it misleads regulators and could impact patient safety.

Best Answer:
An audit trail is a secure, computer-generated record that logs all actions taken on electronic data, including who made changes, what was changed, when it was changed, and why. It supports traceability and accountability.

How to Answer:
Explain that audit trails prevent data manipulation and are a regulatory requirement for systems under 21 CFR Part 11.

Best Answer:
QA ensures data integrity by:

  • Verifying documentation is complete and accurate

  • Reviewing audit trails and logbooks

  • Ensuring SOPs enforce good documentation practices

  • Training employees on ALCOA principles

  • Conducting periodic data integrity audits

  • Ensuring proper backup and access control of data

How to Answer:
Show that QA is the gatekeeper of data integrity, and proactive monitoring is key.

Best Answer:

  • Lack of proper training

  • Pressure to meet targets

  • Poor documentation practices

  • Lack of oversight or SOPs

  • Inadequate access controls on electronic systems

  • Culture of fear or blame

How to Answer:
Mention both technical (like system controls) and cultural (like lack of awareness or pressure) reasons.

Best Answer:
The correct method is to:

  • Draw a single line through the incorrect entry

  • Enter the correct information nearby

  • Add initials, date, and reason for correction

  • Never use white-out or overwrite entries

How to Answer:
Keep it simple, and emphasize traceability and compliance with GDP (Good Documentation Practices).

Best Answer:
Contemporaneous recording means that data is documented at the time the activity is performed. It ensures that the record reflects actual conditions and reduces the chance of error, manipulation, or memory bias.

How to Answer:
Mention that it enhances data accuracy, ensures real-time traceability, and is a core ALCOA principle.

Best Answer:
During a QA audit, data integrity issues may be identified by:

  • Inconsistent entries or missing data

  • Altered documents without proper justification

  • Delays between activity and documentation

  • Lack of audit trail in electronic systems

  • Duplicate records or mismatches in data

  • Poor control of user access

How to Answer:
Show you’re observant, detail-oriented, and aware of both paper-based and electronic records.

9. Quality Assurance Interview Questions in Pharma Industry: Behavioral & Situational Questions

1. Tell me about a time when you identified a quality issue during manufacturing. What did you do?

Best Answer:
In one of the batches, I noticed weight variation in tablets during in-process checks. I immediately informed the production supervisor, stopped the line, and started a deviation report. We conducted a root cause analysis and found that a feeder nozzle was partially blocked. After cleaning, we restarted the line under QA observation. A CAPA was implemented to include more frequent equipment checks.

How to Answer:
Use the STAR method – Situation, Task, Action, Result. Show that you took initiative, followed procedures, and helped prevent product failure.

Best Answer:
I stay calm and professional, focusing on the problem, not the person. I gather facts, review data, and facilitate open discussion. If disagreements arise, I refer back to the SOPs and involve senior QA or cross-functional leads to ensure a fair and compliant resolution.

How to Answer:
Demonstrate emotional intelligence, communication skills, and the ability to de-escalate tension while sticking to compliance.

Best Answer:
During an external audit, an inspector asked for a document that had a discrepancy in signature. I quickly reviewed the logbook, verified the entry with the concerned operator, and provided a clarification note approved by QA. I acknowledged the observation honestly and offered a CAPA plan to improve real-time documentation.

How to Answer:
Show you can think clearly under pressure, take ownership, and act responsibly without hiding issues.

Best Answer:
I follow Good Documentation Practices (GDP), double-check my entries, avoid overwriting, and ensure everything is written legibly and in real-time. I also review documents thoroughly before forwarding them and never hesitate to seek clarification if something seems unclear.

How to Answer:
Focus on your discipline, consistency, and commitment to compliance. Employers value QA professionals who treat documentation seriously.

Best Answer:
I would respectfully explain that even minor deviations must be documented as per GMP and SOPs. Ignoring it may seem small but can have serious consequences. I would insist on recording it formally and finding a compliant way to meet timelines without compromising quality.

How to Answer:
