TaskRabbit Marketplace Community Manager interview questions

After applying online, I was contacted by an internal recruiter. After reaching back out to him with times I would be available, I had to reach out a 2nd time and he attempted to schedule an interview 5 hours from his email. Since that did not work, I reached back out with my availability, but did not get a reply. I emailed him again 3 days later and was finally able to schedule an interview. The interview with the recruiter went well and was very straightforward. It involved talking about the company and my past experience. He said he would then schedule a phone interview with the head of business development. That interview also went well and I was told I would be brought in for an in person interview. However, about a week later, I was notified that they had decided to hire someone else whom they had interviewed in another cycle of interviews and who had turned down the original offer they had extended to her. After all the back and forth, I was shocked that it would come down to Taskrabbit reaching back out to a candidate that had already turned them down. I'm not sure if the title changed, but there is no one on the Taskrabbit Team page under the "Marketplace Community Manager" title.
