I’ve had the same worries a year ago when I was looking for work. I came to Taiwan without securing a job and just searched the internet and canvased around. I only got call backs from the ads I applied via the internet. I also got a lot of “we only hire foriegners”.
This being said I got a job within a week with a franchised chain school at competitive pay. Personally, I think being an ABC is a challenge, but you’ll get work, just hang in there. Plus, I rather get turned down by a school who values skin care over qualifications.
Keep in mind too that most school discriminate since many of the owners and staff don’t speak english, or not very well. A lot of the smaller schools can’t tell how well you speak, and need appearance as proof.
