Holcim Customer Service Manager interview questions

The interview was with one young girl (no experience in real life, just 23 yrs and a lot of internal diplomas) + one lead manager, also woman, inexperienced but arrogant. We discuss one thing regarding the salary and I was paid something else - like (-) 20 € / month = 240€/year lost since they were taken from the salary for meal tickets. Financial illiterate management. No time management. No respect for your time. I've waited for 15 minutes until the interview.
