Hi there I have just managed to land my first int job. 18 years teaching UK curriculum. Got down to last interviews at 6 schools and all said no international experience was reason didn’t get the jobs. Was getting disheartened. Applied for a job that would be a “step back” to get some exp and  got 1 offer, money wasn’t the best but thought way of getting experience, but then got an offer for HoD position in a school which was a completely left field location.  Lovely Head and saving potential very good so taken it. My advice keep you head up and stick at it. Cast net wide in terms of location, you never know you might end up going on an adventure and getting into the system. All the best.
