Tech, from my experience, has a lot of job postings, but its very difficult to actually get an interview nonetheless a job. I’m not entirely sure why its so difficult, as there does seem to be a pretty big need for it across the board. My best guess is mix of companies needing employees but not being willing to hire/train them leading to “fake” postings (alongside those just meant for data collection), and just a generally competitive market right now.
The system started to be phased out in the early 70s, with the last federally funded residential school was closed in 1996 (although there are also the issues caused by day schools to consider). There is absolutely still people around who had a significant part in the system, both in organization and administration, as well as staff directly in the system. To my knowledge, none, or nearly none have been prosecuted for their involvement in the schools.
