Bank of America Sr. Software Engineer interview questions

I was contacted by consultancy and 1st round was Telephonic technical interview. After clearing it, 2nd round was manager +technical round. It also went very well and I was expecting a positive feedback from BOA. But even after multiple follow up with HR and manager over call and mail they were not professional enough to provide any sort of update. I am not sure what it takes to for them to atleast provide update whether positive or negative. Purely a waste of time and efforts. And such a unprofessional HR team of BOA.
