Received interview request via email, met with a few ppl including HR, CEO and ppl from other dept who can't well explain their positions. Had to go there for 2nd time because one person at the 1st time interview cancelled at last minute. After twice interview no word at all from HR, even though sent a follow up email. Overall the entire experience was unprofessional. Many questions they asked were meaningless, I wonder they truly have this position opening.
