how come you have to ask this stuff at the end? wouldn't it make more sense for this information to be provided up front? what does it matter if i'm technically qualified for your job if your team size, structure, tech stack, required availability, etc. isn't a fit? why would you wait until after a tech screen for this? seems like a waste of everyone's time.
