OpenTable Product Manager - Content & Discovery interview questions

Submitted my resume through the OpenTable web portal after finding the job posting on Indeed.com. (No cover letter.) Got an invitation for a phone screen a couple weeks later. Did the phone screen, it went pretty well. Got asked questions like "Why do you want this job?" and "Do you use OpenTable?", the usual. Then the interviewer told me that they would set me up on the next interview and explicitly told me to ping them by the end of the week if I had not heard back from them. Friday rolled around, heard nothing. Monday, nothing. Gave the benefit of the doubt but didn't want to seem like I had forgotten about it so I emailed and gave a nudge. Nothing. Followed by nothing. Very strange experience.
