The work was exciting, every day I had a new client to visit in different cities. Along the fifteen years which I worked there, a learn about the security system, control access and customer relationship. I reported to a manager which delegated to me some tasks to be followed during the month and from those tasks I made my own schedule. The most difficult part of my job was the client's audit which sometimes was not acceptable by the clients. The most interesting part of my job was the challenge of teaching the clients about the security system which my company worked.
