I was once commissioned to teach such a "bootcamp". It was a 4-months duration but 1 day a week. So something like 2-4 weeks total duration. I found out that the students were promised that this was enough to get them a job doing software development and were disappointed when I told them it wasn't. So towards the end, I took some time to explain what was missing and why it will take MUCH longer to even just learn the basics. The organizers were not happy at all that I did that.

To be fair, there were a bunch of students that did listen and worked hard on their assignments and projects and went on to integrate what they learned into their chosen profession and progressed in their jobs. I was very proud of that bunch.

Surprisingly, I wasn't asked by the organizers to teach again. It also didn't help that midway I was asked to switch from teaching web development to machine learning and they didn't really like it when I said "but those are two very different things".
