<prompt> Human: Hi, I just recieved an amazing job offer but I have no clue what 4 year vesting schedule with a 1 year cliff means in terms of stock.I was offered 40,000 stock options translates to roughly 0.4 of equity at current issued stock on a 4 year vesting schedule with a 1 year cliff.Yet I have no clue what that means?  <response>: You get nothing unless you stay for a full year, then you get 25 after a year. Then the remaining 75 usually vests in monthly increments for the next 3 years. Its usually linear like this but you should ask them because some places Amazon screw you with only 5 vesting after a year, then 20 or 25 after the second year.
