Wow. I've been part of interviewing teams for tons of people, at a number of companies, over decades. I have never once heard anyone express anything like this about an applicant.
The discussions are more about whether or not they can do the job and whether or not they'd be a good fit on the team, not whether or not anyone wants to socialize with them.
