I saw an anecdote a few years ago about a hiring manager basically saying, "If you worked happily for a small startup, you will most likely be unable to put up with the bureaucracy of a large enterprise from now on"
I've often wondered how much truth there was to that statement.
I think that was also part of whatever I saw had to say. But I don't remember where I read such a thing, so who knows.
With a larger company you will typically find they have already hired specialists to handle very specific tasks. You can always do some things but more often than not the rigor of corporate structure says "If you need anything done in dev ops, please speak to _Bob_ and he will sort it out".
Jumping from the challenge of constantly adapting to different tasks to being there to only do a single 'role' can be quite jarring.
I did interview at a different startup a couple years ago, which was I think around 100 employees at that point. They claimed to be very lean and quick on their feet, but I got the feeling that we were talking about different levels of volatility.
I suppose the thing that actually keeps me where I am is I have both a very long leash and a high degree of influence. Hard to level-set that against other positions I see listed.
I've mostly worked for startup to mid sized companies in the past, but I decided I'd try to do things differently by cramming leetcode and chasing that fat FAANG pay check. Now I'm kicking myself, this is what happens when you follow money over passion. The silly thing is I'm fine financially, yet I lusted after a job with technology I'm not interested in working on just for the lure of the almighty dollar.
