The hiring process was initiated via external recruitment company. The recruitment company kept the name of the company "Nestle" confidential at first. And when the first interview proved to be successful, I was directed to Nestle office. I was not accepted for the job in the end and this was announced via e-mail. Everything is normal up to now. But it was a great shock when seeing my name was given in cc (instead of bcc) with other rejected candidates. They simply violated the law of the protection of personal data which was unprofessional and unethical.
