Yahoo Senior Software Engineer interview questions

I was referred to this an opening and the hiring recruiter reached out to me. I had 2 phone screens and then invited for the onsite interview. Onsite interview lasted for 5 hours (5 rounds). Few days after the interview hiring recruiter contacted me and was told that i did well and the team liked me and they would like to offer me the position. I was asked not to accept any other offers. I was told that they would submit it for an hiring committee review. I was told that there should be no issue with the hiring committee as the team liked me and it was just a nominal process. I did not hear back from them for few weeks. I followed up with them and was told that it is still in the review. Few weeks later i again reached out to them and was told that the position is filled and they are trying to open a new position for me so that they could submit to the hiring committee. I did not hear back from them and it has been 3 weeks. I tried reaching out to the hiring recruiter but they are not responding to my emails. It was really a bad experience.
