Selectivity
Selectivity is an important concept in chemical manufacturing that measures how well a process produces the desired product while minimizing unwanted byproducts. Think of it like a recipe's success rate - high selectivity means you're getting mostly what you want, with little waste. In job descriptions, this term often appears when companies are looking for professionals who can improve production efficiency and product quality. It's similar to terms like "yield optimization" or "process efficiency," but specifically focuses on getting the right chemical product.
Examples in Resumes
Improved Selectivity in catalyst reactions resulting in 30% higher product yield
Developed new processes with enhanced Selectivity reducing waste products by 40%
Led team projects focused on Selectivity optimization in pharmaceutical manufacturing

Example Interview Questions
Senior Level Questions
Q: How would you approach improving selectivity in a chemical process that's showing poor yield?
Expected Answer: A senior engineer should discuss systematic approach including analyzing current conditions, identifying key process parameters, designing experiments, and implementing control strategies while considering cost and safety implications.
Q: Describe a time when you led a project to improve process selectivity.
Expected Answer: Should demonstrate leadership in process improvement, team coordination, and ability to achieve measurable results in yield optimization while managing resources and timelines.
Mid Level Questions
Q: What factors affect selectivity in chemical reactions?
Expected Answer: Should explain basic factors like temperature, pressure, concentration, and catalyst choice in simple terms, showing understanding of how these can be controlled in industrial settings.
Q: How do you monitor and measure selectivity in a production process?
Expected Answer: Should describe practical methods for tracking product quality, yield calculations, and use of analytical tools to measure process performance.
Junior Level Questions
Q: What is selectivity and why is it important in chemical production?
Expected Answer: Should provide basic definition of selectivity as the ability to produce desired product while minimizing unwanted byproducts, and explain its impact on production costs and efficiency.
Q: What safety considerations are important when working to improve selectivity?
Expected Answer: Should demonstrate basic understanding of chemical safety, proper handling procedures, and awareness of safety protocols in process modification.
