Microsoft Customer Service Representative interview questions

Overall negative experience. Was referred by an MS employee and after 14-day, received an automated email that said there were no jobs that fit at the time. Then a few weeks later received an email from the hiring manager. Had a phone screening with the hiring manager and he said that they would get me in-house. A month went by and nothing and I had disregarded it and moved on. Then I get an email apologizing for delay and that they would schedule me to bring in-house. Interview scheduled a week later and had a call with HR. He tells me that they're looking to move fast and that I should receive results the day after interviews. He had called a little late and was very apologetic for calling me late. Was super nice. Even gave me his phone number to reach out to him afterwards. In-house interviews went fine. Everyone was nice. Had a loop of 3 potential colleagues, one of them a lunch interview. Then they decided they'd have another manager interview me, but it was not the hiring manager, which I thought was odd. At any rate, I did not hear back the next day. I have followed up with the recruiter a few times and it has been a month and a half, and no response at all. Not even an automated "thanks for applying but this position has been filled" or "you weren't a good fit." Just nothing but arrogant silence. While I can infer that there is no offer in the pipeline, I just think it plain RUDE to treat people like this.

1:1 phone interview with the manager first. Then a 5 hour phone/face to face interview with various groups across the company. Each interviewer was different and some were unprepared, did not have my resume or the phone number to reach me at their offices. HR asked basic questions about your background, skills. Marketing asked questions about experience with marketing - and how you would help them with their position. Definitely read and know those thought questions about how to move Mt Fuji- I was asked several of those questions.
