It can be either, so do not treat the request for a call as confirmation of an offer.

Firms use phone calls for offers, rejections, timing updates and requests for additional information. The wording and timing vary by office and recruiter.

Take the call somewhere you can speak comfortably and have a way to note any important dates or next steps. If it is an offer, you do not need to make an immediate decision unless they explicitly require one.

If it is not the outcome you want, use the call to understand what happens next and whether feedback is available. Avoid trying to infer the result from a ten-minute calendar invitation.
