It took me less then a month to realize I was lied to at my interview about what my job would entail. I was too scared of losing my job at the time since I left another company to transfer here (I'm an id–t, I know) so I didn't say anything right away. Later when I brought it up I was just told that things change. That's it.
I'm telling you, leaving my old job for this place is the biggest mistake of my life.
