I graduated from law school (which confers a bachelor's degree in my country) a few years ago.
I then switched to tech soon after (as a software engineer), and now I'm thinking about going back for a Master's degree in computer science or something similar. Most of the schools I'm looking at require three references, and I understand at least one (preferably more) should be from former professors, with a view to assessing your potential to perform academic work.
I have reached out to the tutors in my last two years of law school, but I'm not sure if they still remember me, and it's also an unrelated degree, so I might have a problem there.
After my career change, I was an instructor at a data science bootcamp for a while. A former student of mine from there later applied to a fairly highly ranked US university. He asked me to write a letter of recommendation for his application, which I did, and he was eventually accepted.
I know you should normally look for referees who were in a supervisory position, but I'm just wondering if I could actually ask this former student, if I can't get any other academic references.
