One of the things I value the most about working at startups in my early career is that it allows relatively "junior" folks more exposure to the big picture, and thus stay grounded in reality and not swayed by all the random narratives that are floated around in the corporate world. No matter how smart you are, or how honest and well intentioned the intent of the speaker, it takes experience to be able to parse through these and understand when and how they are relevant to your individual work. I see a lot of folks over the last 15 years who got hired into big tech during boom times, never got anywhere near the critical path of the business, and were exposed to all manner dysfunction by ambitious but incompetent social climbers who swelled the ranks of anything with the whiff of success. In these types of environment, people who just want to do good software engineering work can easily get swept into various dead end buckets of learned helpless, rest-and-vest, burnout, etc.
