It's really great that every reply requires repeated reminders.

After the conversation, they asked what the lowest salary I could accept would be.

They needed someone for a position requiring extensive travel throughout the Taipei area, yet were only willing to offer approximately 25,000 (with no subsidies of any kind, and apparently without even deducting health insurance premiums).

I didn't understand what that self-assessment questionnaire was or what they wanted to learn.

They wasted nearly half a month of the interviewee's time. Even though they had agreed on a response time, they only notified me that I was not selected after I proactively followed up.

Really great—I hope your company enjoys continued success.
