Invited to speak with a PM post final round

I recently completed the full interview process with BCG — including a third-round. I was told the interviews went well, but there weren’t any open projects available for me to be placed on at the time. They mentioned they’d reach out once something suitable came up.

Recently, I was invited to a “coffee chat” with a PM who had recently joined the firm and will be taking on a new project in my industry. The chat went very well and he seem to like me, though he mentioned he wasn’t entirely sure what the next steps would be.

Has anyone experienced something similar? I’m curious how to interpret this — is it typically a positive sign or more of an informal touchpoint to gauge fit?
