Microsoft Software Developer interview questions

Recently I gave four rounds of interview in Microsoft. I went upto managerial round but after that I didn't hear anything from HR.after a week when I called HR,the response I get was "The position on hold,once it resumes we will get back to you". This is the first time I think Microsoft is doing something like this.this is really disappointing and frustrating.

Applied online. Recruiter contacted me and set up a phone screen. The phone screen was for 45 minutes and consisted of puzzles and questions about my resume, past experiences, projects, etc. Got a reply within 2 days that I had cleared the phone round and would move on to the onsite interviews. It took almost 2 months to schedule the onsite due to scheduling conflicts. Onsite interviews started after lunch and consisted of 4 back to back interviews of about 45 mins each. 3 of them were coding and 1 was a design problem. All on the whiteboard.
