They Schedule my interview time at 10 A.M. however i manage to come on before schedule time, when I tell them, I am coming for the interview they told me please call your contact person and sit outside of the office ( I considered that's OK for me).
interview round complete and tell me if you are selected we will call back you. (that's was ok to me), after some days they call me for the telephonic interview at 11 a.m next day but they call me next day around 12 p.m (unprofessional), the person on the other side of the phone told me tell me about your self when I tell her "You have my CV on your desk i guess you go through in to it" she tell me i am not the H.R person I am the M.D.

very unprofessional they are and the office space it too small to move freely fro a single person
