I think it can be hard for smaller departments, such as computing to offer more than a day
I absolutely agree with you.
It does leave people in a ridiculous situation though where the training programme staff want you to get more experience but they can't do anything to arrange that within their school.
I totally understand that a tightly run department (computing / science / anything really) doesn't really need the added hassle of arranging school experience for the benefit of potential trainees when they are already training the current year's actual trainee.
The school have suggested that I apply to be a Cover Supervisor but I am concerned that financially I would struggle financially as the pay is not spectacular.
Also, there is no guarantee that in a year's time I would not be rejected again for a training place.
I was speaking to my neighbour about it and she made two relevant points.
Firstly, as they couldn't offer me a training place and they thought that I could gain the necessary experience from spending a year as Cover Supervisor; she thought that they would have offered me the post outright rather than suggest I apply from scratch.
Secondly, that they didn't offer to give me a training place in 2019 on the condition that I spent a year doing a good job of being a Cover Supervisor.
Also, I am concerned that perhaps it was nothing to do with lack of experience at all and they just didn't want me. Maybe they thought that suggesting this idea was a kinder way to reject me???
Either way, I can't think about it any more until after I have been to my other interview tomorrow.
