What is a startup anyway? It can be anything between a 2 people business without a cent to a company with 500 employees that raised 300 million dollars. Even Airbnb is considered a startup in the media. When talking about these things it's very important to distinguish what stage the startup is in because the experience varies wildly. A pre-seed startup is not the same as a round-X startup.
I don't think working for a big, well funded startup will be that much different than a big corp in terms of work life balance, stability etc.
You have mass firings in Microsoft too.
