Worked at another big Californian semiconductor company for several years. Directors/middle managers, mostly Americans, would always joke about how easy it was to get H1Bs hired and all the shady stuff they did to not have to actually advertise the position. They got great bonuses, life was good.
Eventually, {specific H1B subgroup} made up a significant portion of the company as they always continue to hire more of {specific H1B subgroup} at the expense of everyone else. During a downturn several years ago, there was a tremendous layoff to try to maintain profitability.
Most of the old guard, almost all the older higher paid Americans that didn't make it to the VP level, got axed.
