Business etiquette is completely different in Taiwan (or any foreign country) than it is in the US. Non-specific and incorrectly formatted paperwork will stand out.
To clarify for the OP (to whom it may concern): Non-specific means you didn't make the effort to determine whom would receive the letter and referred to them in a generic manner rather than their correct title and name (surnames are written before their name, which differs from how one is addressed in North America).
Further, incorrectly formatted refers both to the cover letter (which aligns with and promotes (highlights) particular strengths important for the position (such as "the OP has lived there before and is familiar with the customs") and the resume.
It's important to know one's manners and not have the cover letter brag about one's prowess but to instead put forth your accomplishments in a straightforward and modest manner.
Additionally, there is a photo of you dressed well and appropriately for the position placed upon the first page of your detailed three page resume.
This differs from the practice in North America where there is no photo on your single page resume which rather than spelling everything out in complete detail is short and to the point.
A one page resume invites questions and an interview, it also provides one with an excuse to call a week or two later to remind, express interest and ask if there were any questions.
The person answering the call clearly understands the purpose of your call or you'll be accepting another offer and forgetting about them; assuming they are on the ball otherwise it's a flag.
In North America you don't drag it out at length unless you're applying for a job where chattyness is encouraged. Much as here, verbose answers may not be appreciated but there's a few upvotes on a reply concerning if the question had been answered.
Hopefully this edit leaves no stone unturned. Now to simply neglect to reply in the question below that I've updated the answer and I'm on to the next opportunity (opportunity in North America being different from acceptance).

Differences (short list):
- Cover Letters for Interviews in Taiwan
Address the recipient by his or her title such as: Principal, Doctor, or President followed by the surname. Keep in mind that their surnames are written before their names. Mr. Lee Yang-Shu means that the surname is Lee. If you don't know the person's title, use a courtesy title such as Mr. Sir, or Madam. When you sign the letter, make sure that you write your full names.
Adhere to the Taiwan business etiquette when you are called for an interview. They use the interview not only to establish your ability to perform in a certain position, but also evaluate how well you will adapt to their culture.
It is important to research modern manners and business practices, don't rely on a single opinion or link to formulate a plan.
Research and even a few lessons will increase your chances and ease your integration.
