Deloitte Developer interview questions

Asked for second round of interview when was going to attend HR called and said to attend later as panel was not available. No response after that. Wrote mails to HR and even after that no replies. It's funny that a prestigious organization like Deloitte is not at all giving value to candidates time. Similar situation occurred months back, when I attended an interview for a first time for a technology, the panel member said he is not hiring for that technology and to wait for some weeks they will contact me back with the right interviewer. No response after that. This is not what candidates expect from top companies like Deloitte India.
