The below is a comment i saw some time back on glass door-
"They hire a lot of mediocre, college-educated immigrants who think they’re getting a sweet deal by getting sponsored in a western country for a comfortable white collar job.
In actuality, they do work that’s about as mind-numbing and tiring as coal mining, but on a laptop, and for ridiculously long hours. Being in these firms puts a black mark on your CV and is essentially career suicide, which is why they offer some serious packages for white experienced hires who can get them clients, and those same immigrants they hired can’t exit to better firms, but they’re still making a lot more money than back where they came from so they stay.
Basically, they’re growing because of 0 voluntary attrition, employees who are enslaved and do good work so they don’t get fired, and these white experienced hires who were willing to swap their career aspirations with a relatively sweet pay package, but they bring these firms a lot of business"
