Practo QA Chemist Interview: Rounds, Questions and Preparation

What the job involves

A QA Chemist in the healthcare and pharma sector tests raw materials, in-process samples, and finished drug products to ensure they meet quality specifications and regulatory standards. Day to day, they perform wet-lab analysis and instrument-based tests (HPLC, UV, titration), document results in compliance with GMP and data integrity norms, and investigate out-of-specification results. In a health-tech company like Practo, this role may also support quality checks for diagnostic kits, telemedicine sample handling, or digital health products.

Role and Technical Knowledge

1. 1

   What is the difference between QA and QC in a pharmaceutical company?

   Explain that QC focuses on testing and analysis of samples, while QA ensures the entire quality system and processes comply with regulations. Mention that QA is proactive and QC is reactive.

2. 2

   What are the key steps in an HPLC analysis, and how do you ensure data integrity?

   Cover mobile phase preparation, column equilibration, sample injection, and peak integration. For data integrity, mention ALCOA+ principles, audit trails, and no manual integration without justification.

3. 3

   What is the significance of pharmacopoeial standards like IP, USP, or BP in your testing?

   State that these standards provide official methods and acceptance criteria for drug substances and products. Emphasise that you follow the latest edition and document any deviations.

4. 4

   How do you handle an out-of-specification (OOS) result in the lab?

   Describe a phased investigation: first check for lab errors, then manufacturing issues, and document everything as per SOP. Mention that you never discard or ignore an OOS result.

Practical Scenarios and Troubleshooting

1. 5

   You notice that your HPLC system is showing a split peak for a standard injection. What do you do?

   Suggest checking for column contamination, mobile phase pH, or injection volume issues. Mention that you would stop analysis, document the observation, and inform the supervisor before proceeding.

2. 6

   During a routine test, you find that a raw material batch fails the identity test. What steps do you take?

   Explain that you would repeat the test to rule out error, then raise a deviation and quarantine the batch. Emphasise notifying QA and following the SOP for rejected materials.

3. 7

   How would you ensure that your lab records are always audit-ready?

   Mention contemporaneous recording, no overwriting, using indelible ink, and following ALCOA+ (attributable, legible, contemporaneous, original, accurate). Also mention regular self-audits and training.

4. 8

   A colleague asks you to skip a calibration step to save time. How do you respond?

   State that you would politely refuse and explain that calibration is mandatory for valid results and regulatory compliance. Suggest escalating if pressure continues, as quality cannot be compromised.

Behavioural and Teamwork Questions

1. 9

   Tell me about a time you had to follow a strict procedure even when you were in a hurry.

   Use a STAR example from college lab work or internship. Highlight that you prioritised accuracy and compliance over speed, and mention the positive outcome.

2. 10

   Describe a situation where you found a mistake in your own work. How did you handle it?

   Show honesty and accountability. Explain that you immediately reported it, corrected the record as per SOP, and learned to double-check your calculations or documentation.

3. 11

   How do you handle working with a team member who is not following safety protocols?

   Say that you would calmly remind them of the protocol and report to the supervisor if it continues. Emphasise that safety and quality are everyone's responsibility.

4. 12

   Why do you want to work as a QA Chemist in a healthcare or pharma company?

   Connect your interest in chemistry and quality to patient safety. Mention that you want to ensure medicines and health products are safe and effective, and that you value precision and ethics.

HR and Career Fit

1. 13

   What do you know about our company and why do you want to join us?

   Research the company's products or services, especially in healthcare or pharma. For a company like Practo, mention its role in digital health and how quality assurance supports trust and compliance.

2. 14

   Where do you see yourself in three years as a QA Chemist?

   Show ambition to grow into a senior QA role or specialize in areas like auditing or regulatory affairs. Mention continuous learning of new techniques and regulations.

3. 15

   How do you handle repetitive tasks while maintaining attention to detail?

   Explain that you use checklists, take short breaks, and remind yourself of the impact on patient safety. Give an example from studies or previous work where you stayed accurate.

4. 16

   Are you comfortable working in shifts or in a manufacturing plant environment?

   Be honest but positive. If yes, express willingness to adapt. If not, mention your flexibility for other roles. Emphasise that you understand the demands of the pharma industry.
