Far Out Solutions interview questions

it was a good process at the beginning then it turned into a horrible experience. Recruiter contacted me to set an interview date then delayed the date 3 times in the same week for no clear reason. Kept asking for the feedback follow-up but no responses from their side and when i asked again they said that there is no feedback for you and when it`s done we will contact you again and finally i got rejected for no clear reasons too.
