Downstream Processing
Downstream Processing is the part of biotechnology production that involves purifying and preparing biological products (like medicines, vaccines, or proteins) after they've been initially created. Think of it like a cleanup and packaging process - after scientists make a biological product, it needs to be separated from other materials, purified, and made safe for use. This is similar to how coffee beans need to be separated from coffee cherries, cleaned, and packaged before reaching stores. It's a crucial step in making biotech products ready for use by patients or consumers.

Example Interview Questions
Senior Level Questions
Q: How would you approach scaling up a downstream process from lab to manufacturing scale?
Expected Answer: A strong answer should discuss risk assessment, considering equipment limitations, maintaining product quality, and managing costs. They should mention experience with previous scale-up projects and problem-solving approaches.
Q: How do you handle process deviations in downstream processing?
Expected Answer: Look for answers that include investigation methods, documentation practices, implementing corrective actions, and preventing future occurrences while maintaining product quality and safety.
Mid Level Questions
Q: What methods do you use to optimize product yield in downstream processing?
Expected Answer: Should discuss different purification techniques, process parameters adjustment, and how to balance product quality with efficiency. Look for practical examples from their experience.
Q: How do you ensure product quality throughout the downstream process?
Expected Answer: Should mention quality control steps, testing methods, documentation practices, and understanding of regulatory requirements for biological products.
Junior Level Questions
Q: What are the basic steps in downstream processing?
Expected Answer: Should be able to explain the main stages: separation, purification, and polishing in simple terms, showing understanding of the basic workflow.
Q: What safety considerations are important in downstream processing?
Expected Answer: Should demonstrate awareness of basic safety protocols, contamination risks, and proper handling of biological materials and equipment.
