My experience here was very disappointing because besides my gastronomy job I did the test lead job and project manager + I also came up with the idea for the firm to make our job easier, I offered to call or send e- mails to buy bulk. Everything okay until I asked for an increase in salary what was absolutely normal after 1 year in the company plus two more years back and all that I did extra, that I tried to do for 3 months in these 3 months I did just what what had to be on my gametester post. In the last 3 months I asked for what I did, I was threatened that if I insisted with this I would be kicked out, because I insisted on something normal, I saw that there is still an indignant guy on something more serious, it is inadmissible so!
