Was contacted by email a month after applying. I had a phone interview with 2 separate teams. Both went well. Had two second round phone interviews, one with each team, about a week after the first one. Went well also. I was told by HR I should know the result for both teams within a week. Now, it has been almost 3 weeks since that and I've contacted HR multiple times through email with no response. When I called them they told me they are still interviewing other candidates and I should know the result soon. I have a deadline for other offers so I'll have to accept those offers because Yahoo has a horrible interview process and they do not care about any time constraints or the fact that the interviewee has other deadlines. Don't apply for this company, you'll be wasting your time. I don't know what's going to happen to my result but if they end up offering me the position over the next week or so I will decline it.
