Founding engineer of nearly 5 years for a startup that is series C level.

Management didn’t understand why some engineers were more expensive than others, especially if work can be outsourced.

The founding engineer had 2% company stock in their offer letter but were given 180k shares vested.

Why would the offer letter say it’s 2% of company shares, but it ended up being ISOs that were granted?

Also how does one find out if the number of shares is equivalent to what 2% would represent in the first fundraising round? Ie how can this be confirmed if employee is laid off
