So here are my assumptions, correct me where I am wrong. This is MBB-specific.
Pre-interview I assume interns go through resumes and then the prioritized resumes are invited to the test. Poor scorers are automatically eliminated. The rest are discussed in an HR meeting for interview invitations.
The first round interviewer provide a thumbs up or thumbs down to HR. If two thumbs up, candidate gets through automatically, if one thumbs up, interviewers get together with HR to discuss and they make the decision together.
Second round, same thing happens. Partners sit down with HR to discuss and they make the decision together.
These are only assumptions, please correct me where my assumptions are off. Besides this. Is my assumption that HR still has decision-making power after interviews are handed out correct?
