X interview questions

I originally applied through a referral for a position on the MMS sales team. I was sent questions via email to answer about my background in advertising and opinions on Twitter's value proposition in the digital advertising realm. After passing that step, I was contacted by a recruiter via phone who gave me the usual background questions and we discussed my answers from the email in detail. He told me he would connect with the hiring manager and get back with me at the end of the week. A week and a half later after no word, I reached out to the recruiter. I was then sent an automated rejection letter. Three weeks later, a different recruiter emailed me about a new position. She called me and told me about the new position and scheduled my in-person interviews that week. I went into the office and had back-to-back 30 min interviews with 2 folks from the team and the hiring manager. They were very friendly throughout the whole process, extremely straight forward, and welcoming. No trick questions. Just wanted to get to know me, my background, my ideas, and capabilities. I was offered the position that night.
