I have been working at Acer (Taiwan HQ) full-time (More than 10 years)
Acer is a tough environment to work in, especially if you're remote. That said, if you can align yourself properly its possible to make change pretty quickly.
Historically Acer was a very top down management style; that's starting to change under the new leadership where management is more open to ideas but it really depends upon the dept you work in. Also, being remote is tough as lots of decisions are made in real time in Taipei.
Advice to Management
Focus on retaining those employees who will be your long-term assets. It's been a challenge to hire in new staff due to Acer's recent performance; those who stay are loyal but that needs to be both ways to ensure commitment.
I applied online. The process took 4+ weeks. I interviewed at Acer (Taiwan HQ) (Taipei (Taiwan)) in November 2014.
First there was a simple phone interview and then an in-office interview with a short test. I met with a few other people in the office and had a chance to talk with some of them about the company, find out what the work culture was like. One consideration is that the office is located a bit outside of the city limits and is hard to get to. It's pretty inconvenient unless you have a car or scooter.
