Very very bad consultancy during scheduling interview they will take care much and do everything and they will follow-up with us. Selected in interview 2 rounds completed and gng to have final discussion during interview but no use they just simply told like that and no update even after following up for 3 weeks. Very bad even consultancy will say same answer we didn't get any update once we tell our name. Very very very bad experience i have faced with this consultancy...
