Your customer is the placement cell, not the student
Campus hiring inverts the usual recruiting relationship. You are not persuading individuals to apply; you are persuading an institution to give you access, on a date, ahead of other employers. The placement officer decides which day you get, which branches sit for you, whether students who accept your offer may keep interviewing, and how quickly your queries get answered during a drive.
That relationship is built over several seasons and, in most companies, it lives entirely inside one recruiter. When they change roles, the institution notices before you do: emails go to an address nobody monitors, the slot request arrives late, and a campus you hired thirty people from last year gives you an afternoon in week three. Holding institutes as accounts with contacts, commitments and history is not administrative tidiness. It is how a company keeps access it spent years earning.
Slots go to whoever confirms first
Season planning is a race with a fixed calendar. Placement cells build their schedule in a short window, and the employer whose paperwork, job description and package details arrive complete gets slotted before the one still waiting on an internal approval. Running slot negotiation as a pipeline — outreach, details shared, slot requested, slot confirmed, pre-placement talk scheduled — makes the bottleneck visible while it can still be cleared.
