Once you start a job, what is the correct level of contact to maintain with the staff who interviewed you but are not in the specific team that you joined?
Is a "hello" whenever you see them around the office expected? Is anything less considered rude? What about a single "hello" when you first start and then months later turning into no "hellos"? Keeping in mind, these will be folks who I spoke to for an hour tops - several months ago, and I have poor social skills.
