P3 Group Java Developer interview questions

Such a worst experience. I did interview at Umlaut Private limited which is formerly called as P3 group.i have completed 2 technical rounds in a day and then they have told me that they will get back to me. after 2 weeks again I got call to come for managerial discussion on that day I did HR package discussion. They said they will soon let me know the progress of job application. But till now I didn't got any response from them even after mailing them several times they didn't responded back. Atleast give respect to the one who attended interview , this seems very disrespectful by not even replying to the mail. Positive or negative it's a basic manners to respond for the mail. Worst company , fraudulent interview process just waste of time.
