It is up to the USCIS, but usually there will be an interview.

I agree with Mr. Shusterman ... probably yes, there will be an interview.

It is correct that you will very likely be interviewed. Moreover, concerning your question about who must attend, although there is generally no requirement that the petitioner attend the interview for a sibling petition, this can be advisable because otherwise the USCIS interviewing officer may issue a request for additional evidence, to confirm that the petitioning sibling is still alive. If not present at the interview, often this evidence could take the form of a dated, notarized affidavit.
