HR forgot the first calling for 2 times. When she sent mail to let me choose a time for the first time calling interview of 15 minutes, there is only the earliest time after a week, it is wired. That day she did not call after i sent an message to her email, almost an hour later, she called and let me go to make appointment on line, very rude attitude on the phone. I chosen another one, also have to wait one week, Today, same thing happen. Not specialist method to work. From today, this company is on my black list. Since a HR calling appointment need waiting for a week, that means, they need hire everyday, that means it is not stable job. People will leave the company too quickly.
