Usually for large acquisitions like these the employees are kept on the same vesting schedules they were already on (especially if the company is so young). There is probably additional stock options issued for retention on top of this. So, if you have been there for 2 years, you are probably 50% vested, 1 year 25% etc. Typically if you have not reached your cliff, it is kept in place.

There are some circumstances where in a big acquisition like this founders or key employees are asked to re-start the vesting clock on their shares. This is more common in small buys but can happen in big ones too. In this case you get some payout for e.g. the 2 years you were there and then the rest of your stock (and maybe a refresher) get spread over 3 or 4 years.

In terms of payout, if you assume by series C that 50-75% of the company was sold to investors then $1.5B to $2.25B will go to investors and the remaining 750 million to $1.5 billion goes to founders and employees. Obviously this is a huge range and you need the cap table to know what really happened.
