What should I do if I get an offer for OJT but I’d really like to wait for a different role or company that I’m more interested in?
If you're already in Week 4 and your last class is next week, your OJT is starting very soon. This means you need to secure something within this week.
My advice is to follow up rigorously on all the past interviews you've had today and tomorrow. If you don't receive any responses, it's best to accept the OJT offer you currently have. This is the best option at the moment and no guarantee you'll get any other offer.
It's a temporary role for 3 months anyways, and if you focus your energy on excelling there, you might be pleasantly surprised by how much you enjoy the role and the potential opportunities for growth within the company.
In any case, you should then spend your effort on securing a full-time role that you're happy with by 20 Dec 2024.
