I'm ex-Infosys from that period. 20 somethings now are fitter, more health conscious than we were. I think there were more smokers/drinkers then amongst us. (Although there are more women smokers/drinkers now than in the 90s/2000s). We slogged like hell. 15 hr workday was routine. I spent 50+ hours in the office once. Don't be misled by 90 second videos. It WAS a great time to work though, but that was because we had humbler backgrounds than the average employee now and we had more/better opportunities because the industry was nascent. My first onsite trip was before I completed my first year in Infosys and there were others in my batch who went before me.
