FIITJEE Database Architect interview questions

they called me on weekend Saturday for face 2 face interview , I reached there 10 minutes before time , got shocked no one there you need to talk with their guard and you need to keep reminder him , after 1 hour of long waiting i did not see any hr comes to attend me so finally I left this place, this is really worse experience i ever faced in my life, they are totally unprofessionally . they just wasting our time , I do not think they have any real requirements ?
