Very sketchy interview. The "job" involves using your own money to buy, rate then return items on a digital store to influence ratings. If its not an overt scam by just refusing to give you any money, its a work environment that it easy to deny payments. You only get your salary if you work 6 consecutive days, and it would be possible to rig the system to give you high value items that you need to put your own money into until you can't afford to continue and they won't have to pay you. Again, assuming any of this is real. Be aware, as they drop the truth about having to spend money quite late in the interview process. Be wary of any "data entry" jobs in the meantime
