Microsoft starts vesting immediately at 20% every 6 months. Amazon, take note.

Are you sure? This means the whole grant vests in 2.5 years. Their vesting period used to be much longer than that.

checking myrewards, some are on the 20% schedule every 6 months (for 2.5 year for full vest) and some are on the 10% schedule (for 5 year for full vest), and some are on a 5% schedule every 3 months (for 5 year for full vest).
