Assay Development
Assay Development is the process of creating and improving laboratory tests that help detect or measure specific substances in samples. Think of it like creating a recipe for a scientific test - scientists need to figure out the right ingredients and steps to get reliable results. These tests are used in many fields, from medical diagnostics (like COVID-19 tests) to drug development and food safety testing. When someone mentions assay development on their resume, they're talking about their experience in designing, optimizing, and validating these laboratory testing methods.

Example Interview Questions
Senior Level Questions
Q: Can you describe a challenging assay development project you led and how you overcame the obstacles?
Expected Answer: Look for answers that demonstrate leadership, problem-solving abilities, and understanding of the entire assay development process from planning to validation. They should mention team coordination, timeline management, and how they ensured quality results.
Q: How do you approach assay validation and what factors do you consider most important?
Expected Answer: Senior candidates should discuss the systematic approach to proving a test works reliably. They should mention accuracy, precision, specificity, and regulatory requirements, plus experience leading validation studies.
Mid Level Questions
Q: What steps do you take when optimizing an assay?
Expected Answer: They should describe a methodical approach to improving test performance, including adjusting conditions, identifying variables that affect results, and using controls appropriately.
Q: How do you document your assay development work?
Expected Answer: Look for understanding of laboratory notebooks, standard operating procedures (SOPs), and the importance of clear documentation for others to follow their work.
Junior Level Questions
Q: What basic laboratory equipment are you familiar with for assay development?
Expected Answer: Should be able to name common laboratory instruments and their basic uses in testing, such as plate readers, pipettes, and analytical instruments.
Q: How do you ensure accuracy in your laboratory work?
Expected Answer: Should mention basic laboratory practices like proper calibration, using controls, following protocols carefully, and double-checking their work.
