This is what i know, hope it helps
Congrats!! i think u almost got the offer, coz they won't invite u if they dunt want u.
as long as u pass the 2nd interview, u r almost there. VP will just meet u to have a look only.
1. tech 叫我去orientation是什么意思?offer的可能性有多大啊?
nowadays TECH provides candidates with this 2-day orientation after they pass the 1st(section manager) and 2nd(engineering manager) round interview. normally u will be assigned to a senior engineer from the same section, and follow him to have a feel of what is going on during a typical day in TECH.
tech just want to make sure that new guys who eventually accept the offer will not quit shortly, since they already have a rough idea abt the company beforehand. Also, ur future colleagues will have a chance to interact with u, and i believe the section manager will ask for feedback from the one who guide u in the two days.
2. tech orientation都干什么啊,我之前要准备什么,有什么要注意的啊?
actually u dunt have to prepare anything(if u want, can bring a notebook for u to write something u feel important), make use of the 2 days to attend meetings, visit fabs(especially important if u apply for manufacturing or process engr), talk to/ask other engineers, have lunch and dinner at its canteen, etc.. Dunt worry, ur boss will assign someone to take care of u.
lastly, although i think this 2 day session is more for u to observe the company, u r observed as well. u will get the offer as long as u dunt do anything unusual.
good luck :)
