OpenTable Account Manager interview questions

My interview experience seemed to mimic a lot of the interviews echoed on here. I made it all the way to the final found: first via phone call, next HR, then director of Sales, and finally two DMs. It seems like they are looking for someone “likable,” and perhaps interview a lot of people at a time. Most of the questions asked were on here, so I felt well rehearsed. I felt confident that everyone I spoke with really liked me -except- one of the DMs. He grilled me on the product, which I did research, but his tone seemed hostile and made me lose confidence in myself. He seemed to overcompensate for being 10 minutes late to the interview to be honest. At a certain point, he just stopped letting me talk, despite us being short on time. It felt super demeaning, and I’ve never encountered anything like that in an interview. My experience with everyone else made me really excited, so when I didn’t get the job it was pretty soul crushing to say the least.
