Genepharm Quality Control Analyst interview questions

I recently had an interview with Genepharm, and unfortunately, the experience was less than satisfactory. The interviewer was quite abrupt and asked if I had experience using HPLC. Although I explained that I was familiar with all the components of HPLC, I hadn't had hands-on experience using it. He labeled me as untrained, which I found unprofessional and discouraging. Overall, the interview did not go well, and I left with a negative impression of the company's interview process.
