Applied through a job posting social network, received a call next day to schedule an interview, got hired 3 days later after completing medical and psychological tests. Initially there was a panel with the General Manager and the Process Unit Manager and a HR Representative asking different questions and was more a conversation type interview, rather than direct questions. Then the HR Representative called back to schedule a second and final interview where the offer was made after completing the psychological tests, between those dates, I was asked to perform a drug test at a selected laboratory.
