X Account Executive interview questions

One 30 minute phone chat with recruiter, very simple and fluid - just covering the basics. Four separate interviews on site, each 30 minutes long. This included Role play presentation and questions The first 3 interviews went exceptionally well, answered every question with ease. The 4th guy interviewing was tough and appeared to want me to fail. He wasn't satisfied with the answer to his question 'If you got the job - what would be the first thing you'd do?'

I was contacted by a Twitter recruiter on LinkedIn. A recruiter than called me after I responded to that InMail, she told me more about the role and the process. She then set me up with the second stage - a phone interview with the Sales Manager. We had that call, and he told me it would be soon after that I would hear back. A week later I contacted the recruiter asking for an update. She responded immediately to tell me that they would like to bring me in for onsite interviews as the phone interview went well. I gave her various date and time options. I didn't hear back, and chased two weeks later. I still haven't heard back, and that was two months ago.
