Pitney Bowes Advisory Software Engineer interview questions

There were two technical rounds and one HR round. In the technical round first basic questions were asked on Angular and Java Spring boot. In the 2nd part more advanced questions were asked on Angular and Java. THen HR round happend.

I have been contacted by a consultant and asked to appear for an interview on a very next day. I did go there and appeared for all the rounds. After two technical rounds, there was one managerial round followed by the HR round. Then after the HR round, I have been informed that I need to fill a form which company HR will send me over the email and I am allowed to leave for the day. But even after a few days when there was no communication, I reached out to consultant to confirm if they have provided any feedback for me or not? And then they told me that the company is saying that nobody has got selected for the position I have applied for and thats it. So even after spending my whole day at their office this is something I was not expecting at all. Company wants their employees to be honest to them but what are they doing with the candidates like us is totally unprofessional and unacceptable. There should be some authority in place where such issues can be addressed otherwise candidates like us will continue to be feel cheated.
