Biofourmis Technical Support interview questions

Very unprofessional. They didn't even sent me a link or any instructions to attend the interview. When the time came I requested for them to send me the instructions. I requested to reschedule since they didn't provide anything. Immediately they sent me a rejection email they moved on to other candidates. I got a call from a lady on a random number saying to call her back since she was part of biofourmis saying she was being late. I'm like how am I suppose to know you guys were gonna call me. I was already thinking it wasn't gonna happen. No link to attend an interview. unexpected call. Very unprofessional company.
