Amazon Warehouse Associate I interview questions

fill out application online and take a personality assessment. Got email offering job to me contingent on background check and drug test. Scheduled appointment where they showed short film presentation then administered swab drug test. Got email congratulating me for passing both and said I would get email with start date soon. Two days later got email saying not hiring for 6 more weeks??

no interview just drug n background test hiring takes about three weeks some of the agencies like integrity only take a week high turn over great medical benefits better then almost any other company
