How long is the probation period for Karl Meyer (Changzhou) interns?

I advise interns not to go to this company. 1200.6 months internship, leaving after one year. Change jobs frequently and go to job fairs frequently. In the past two years, I have often seen Carl recruit interns, and many bottom positions only recruit interns, obviously treating interns as cheap labor. Anyway, there are so many people graduating from six schools here every year.
