LANXESS Process Engineer interview questions

Gave a fundamental process test and while I took the test proceeded to interview me at the same time. 8 years of experience in this type role and the test was easy but took it as an insult to my character and intelligence.

Poor audio quality during interview. Difficult to understand questions. Interviewers were hard to understand. Overall not a very pleasant experience. Interview was on time and everything but I couldn't get answers to any of my questions because the audio quality was soo poor and the interviewer was very hard to understand
