Yelp Project Manager interview questions

Their interview process is low quality. When interview schedule was updated, the interviewer’s name and position should have been as well, but that did not happen. As a result, I ended up meeting with someone from a different function who did not clarify the reason behind. It was a shock because it completely changes my preparation for types of answers. This person was yawning, distracted by surrounding environment, and probably responding to chats on the side also. Interviewers answers to my questions were vague and lacked relevance. Not sure if the company's solving customer problems or if it is more focused on leveraging collected data for company growth only.
