When I started in the chemical industry I worked in Regulatory affairs, it was one of my first jobs. The people in charge of guiding me did not know how to transmit the knowledge correctly, even though they were dedicated to it. Doing a job without fully understanding what I was doing was quite an unpleasant experience. I swore that I would never work in security again.
Fortunately, circumstances led me back to a similar position, but at another company. This time everything was very different, I fell in love with my work.
The person in charge of training me, and who I was going to replace when she left, did know what she was doing and explained it to me so well, that I began to see this sector as if it were something totally different from what I had known until then.
