Hi guys! I guess I'll check in. I lurked around these boards last year and it was nice to know people shared my hysteria.
I'm also an ETA candidate for Taiwan. I was recommended last year, but ultimately not selected. I'm reapplying this year with (what I think is) a stronger application, and I've been recommended again.
I can confirm that there is no interview for Taiwan ETA candidates. Last year we were notified of decisions around the 2nd week of April. The notification times vary based on program. For example, some European countries are notified in early March, some like South Korea ETAs are usually notified late March, and Chinese and Taiwan programs are usually late April to early May.
Good luck all! Don't stress out now, we still have two and a half more months to wait
