Batch Process
A batch process is a way of making biological or pharmaceutical products where all ingredients are added at the start and processed together as one group (or "batch") until the final product is complete. Think of it like baking cookies - you mix all ingredients at once and bake them together, rather than adding ingredients continuously. This method is common in biotechnology because it allows careful control of each production run and makes it easier to track quality. Companies use batch processing for making medicines, vaccines, and other biological products where consistency and quality control are extremely important.

Example Interview Questions
Senior Level Questions
Q: How would you handle a deviation in a batch process?
Expected Answer: A senior professional should explain the importance of investigation, documentation, and corrective actions. They should mention quality control procedures, regulatory requirements, and how to prevent future deviations while maintaining production schedules.
Q: How do you optimize a batch process for scale-up?
Expected Answer: Should discuss analyzing current process parameters, identifying bottlenecks, considering equipment capabilities, and maintaining product quality during scale-up. Should mention risk assessment and validation requirements.
Mid Level Questions
Q: What parameters do you monitor during a batch process?
Expected Answer: Should mention key parameters like temperature, pH, pressure, mixing speed, and how these affect product quality. Should understand normal operating ranges and when to make adjustments.
Q: How do you ensure batch-to-batch consistency?
Expected Answer: Should explain standard operating procedures, documentation requirements, quality control checks, and the importance of following established protocols exactly.
Junior Level Questions
Q: What is the difference between a batch process and continuous process?
Expected Answer: Should explain that batch processes have distinct start and end points with all materials added at once, while continuous processes run constantly with continuous material flow.
Q: What documentation is required for batch processing?
Expected Answer: Should mention batch records, standard operating procedures, and basic GMP (Good Manufacturing Practice) requirements for documentation.
