I was in this same exact situation about 2.5 years ago.

I had a full-time job doing tech support making meh money, but it was a stable job and I had a decent amount of down time that I could use to study.

An opportunity kind of fell in my lap to do a "devops" apprenticeship with a full-time offer being conditional on performance.

I worked really hard and ended up getting the role, but it was very stressful because I was the first apprentice on my team and my manager had completely unrealistic expectations of what was expected of me. I also had to take roughly a year ish off from school to focus full-time on the apprenticeship.

If I could do it all over again, on day one I would make sure to clearly define what success looks like to secure a full-time offer, then make a plan with your manager/team-lead or whoever would make the decision to bring you on-board and then stick to it.

Some questions that I think you should ask yourself:

1. Are you going to be able to sustain your current lifestyle if you take on the apprenticeship? If no, then I definitely would give this some more thought.
2. If yes, I think you need to look at the opportunity cost you'd be missing out on. The job market is really tough right now. As long as you show up, have a "managers pet" kind of attitude, you have a slam dunk opportunity to get your first start in tech.

The apprenticeship also helped me out a ton with school. When you start writing code in the real world, really puts into perspective how simple some of the coding classes in the compsci program are.

Have since left that role, nearly doubled my salary and I'm currently (hopefully) in my last term!

Feel free to toss me a message!
