It's a good sign that you either picked a large enough spread of roles, roles you were well qualified for, or both. This is totally me speculating, but I think one of the reasons that almost everyone who gets asked "would you be willing to do qsfb/custodial/etc?" and says yes ends up getting it, is because they weren't randomly asked that question. It possibly had to do with them having minimal work experience and recruiters wanting to give them the maximum chance of being hired. But if also definitely depends on the person who's interviewing you.
So yeah, I'd take it as a good sign.
