Pharmaceutical Scientist Interview Questions

Sample answer to the question

Yes, I am familiar with several laboratory techniques that I have utilized in my work. One example is spectrophotometry, which I have used to measure the concentration of a substance in a solution. I have also worked with HPLC (High-Performance Liquid Chromatography) to separate and analyze different components in a sample. Additionally, I have experience with GC (Gas Chromatography) to identify and quantify different compounds in a mixture. These techniques have been essential in my work to analyze and characterize various pharmaceutical formulations. I have also used them to evaluate the stability and purity of drug substances. Overall, my experience with these techniques has helped me to contribute effectively to the research and development of new drugs and medications.

A more solid answer

Certainly! In my previous role, I utilized several laboratory techniques that are highly relevant to the pharmaceutical industry. One of these techniques is spectrophotometry, which I used to accurately determine the concentration of active pharmaceutical ingredients in various formulations. For example, I successfully employed UV-Vis spectrophotometry to quantify the amount of an antibiotic in a drug formulation, ensuring its potency. Another technique I am familiar with is HPLC (High-Performance Liquid Chromatography), which I applied to separate and analyze different components in complex mixtures. This was particularly useful when characterizing new drug candidates and identifying impurities. Lastly, I have hands-on experience with GC (Gas Chromatography), which I used to analyze volatile compounds in samples. This technique allowed me to assess the purity of raw materials and finished pharmaceutical products. By regularly employing these techniques, I was able to generate accurate and reliable data, contributing to the development of safe and effective medications.
