Where I worked we had grad students come in for 3 months to get there work experience quota to come credentialed, they new very basic autocad we had to hold their hand but by the end of the 3 months we were giving them tasks and they were producing good work, obviously the task was appropriate to the skill level but it meant we did not have to do it and another project was completed. Around 50% were asked to stay on with us, the others did comment that they also got jobs as working for us was seen as a high quality employer on their resume. They were like a sponge and just soaked up what they were shown. "people that could learn things super fast."
So if it does not work out at the 1st employer just get up and try again.
