Recruiter schedule the interview without full information like who to contact at the location.recruiters are lazy and do other stuff like company meetings etc which people have no idea, oh yeah and Hiring managers have people in mind already(who work internally) to hire them, so they just interview you for formality because the company do have policy to interview certain number of people before close any requisition, so don't think you will get offer even you did awesome, these won't be same for all roles but few for sure.
