Get a job at somewhere that is busy. I feel an FI rating is a licence for you to learn as much as anything else and for that to happen you need repetition.
The first place I ever worked I logged 24 hours in 8 months of employment it simply wasn’t enough and I always felt rusty.
You also want a work environment where you can ask the other instructors questions and don’t get ridiculed for lack of knowledge.
Unfortunately in today’s environment you can’t really pick and choose so well done for getting a job.
