I've worked for large companies that do it both ways. When I knew what group I was going to, it often ended up changing within the first year of my arrival anyway through restructuring, re-prioritization, etc. So I've decided it's generally irrelevant - nice to have, but not actually that important. It's more important to be ok with the larger company culture.
