I think you are right. it is a functional part of

a drug company.
My real problem is I got an interview with a drug company. I never worked in pharmceutical industry and they know it. What should I do if they ask question about CMC. In the job description it says knowledge of "Cross-functional comprehension of other CMC groups"is needed .
By the way what TRA stands for as an analytical instrument in a drug company?
I really appreciate your help.
