Went to this place for a interview HR lady had me come in last minute. She took me back to the warehouse for interview she didn t even know the job description or what the company does. So a lot of awkward silence and she kept sayIng I wish the production manager was here to give you a better run down. My question is how the hell are you a HR manager and you don t know nothing about the company or how it runs that s embarrassing and horrible and don t waste peoples time bringing them in for interviews and stringing them along horrible business practices.
