this course is a valuable guide when hiring. the most i learnt will help me in the work are:
1. ask and how to ask work related with the positon questions: avoid the answer Yes and No questions; try to lead the interview and have the candidate to talk as much as possible to get more information/data about the candinate.
2. use structured and unstructured interviews for different postions;
3. after send the formal offer letter, still can continue to receiving more information from the new hired person to make sure the candinate and company's goal match.
