It doesn't matter. Most jobs even at those companies were not in the interesting areas you heard about. For every one person at the cool jobs there were thousands elsewhere who had regular deadlines and a regular job. Odds are you wouldn't have had the cool job even if you were born in the right era.
Better advice: when interviewing ask questions when they ask if you have any! Find out what the job is really like.
Ask what hours they normally work - if they give exact times that means they are strict about the times. If they give a lot of hours that means you are expected to work a lot of hours. If they give a range that means they really have flexible times. If they talk about leaving early for their kids third grade events that means they support families.
Ask what they really wear - this is clue to what the dress code is like.
Ask about the perks you care about. I don't play ping-pong so won't mention that perk if I'm interviewing you, but if you ask I can tell you that there are regular tournaments and people do play games here and there, but the tables are empty in the middle of the afternoon: if you care about this perk ask, otherwise focus questions elsewhere.
There are a lot of great jobs. There are a lot of bad jobs. There are jobs that you would hate for reasons that the people who work there don't even care about. There are jobs you will think are great that others will hate.
Yeah, but I mean after decades of experience, you already know how to do those things, and they're fairly basic stuff to know and learn from.
Was thinking more "Imagine you have 30 years of experience and casually looking for the next Bell Labs, what to look out for when there are the company?"
If you have 30 years odds are your real worry is can you afford to retire. I'm not quite there but I'm looking at my accounts. I don't need a fun job - I hope not to be there long. maybe I'm worng, but I believe even the best job can't compare to working on my own projects. (Though they will also have bad days)
No, I'm already "retired" as in I don't have to work to survive. Right now I'm contracting on fun/interesting projects that gets passed to me and idly looking for the next Bell Labs to join for fun :)
