I've had similar repayment terms on every signing bonus I've gotten. Especially at large public companies, a huge chunk of your comp is either a bonus at year end or stock on a vesting schedule with a 1 year cliff. When switching companies, it's fairly common to get a sizeable signing bonus to compensate for the reduced cashflow for the first 12 months.
