When your boss asks you to design an assay to detect a mutation using PCR, provide a list of 3 things you will do before testing and optimizing begin.
Always be prepared for the interviewer to ask you situation- and knowledge-based questions to understand how you outline your process and how well you can explain concepts to others. As new and improved assays are constantly being developed and implanted in laboratory research and clinical settings, the interviewer wants to see what three things you will do before testing begins. Before you respond, ask the interviewer whether or not this is a diagnostic assay with FDA regulations so the interviewer knows that you understand the difference between clinical and research. Then you will be prepared to formulate your response.
"In this case, I would first review current literature to understand what is currently being used to test the specific mutation in question. Then, I would evaluate the necessary and available equipment, reagents, and resources needed. Finally, I would write a protocol for the procedure."
