While in training, you are observed all the time. You feel as if you are still in school. You are only hired if you sign a non-compete which prevents you from working at a different CRO for a year in the USA. Some HR will also state your salary expectations are to have a 20-30% raise after completing their 4 month training program. However, in reality you do not see that pay raise until after working 2 years there to align with what competitors would be offering you. They will also not state this in writing only verbally because if it is not written down, it did not happen. You will most likely only see a 1.5-2.5% raise if you have not already been fired.
