Not 996, but some of the h1bs from India go through something similar 5 days a week. Many of them have to attend 'offshore calls' with the team in India which usually starts around 10 pm and goes till midnight, in addition to the regular 9-5 work. One h1b guy I know had his schedule like this - attend early morning 1-1.5 hour meetings at 6.30 am on 3 days of a week, work from 9/9.30-4 (sometimes 5 or 6), attend offshore calls from 10pm that sometimes go beyond 12 am. He worked like this for almost 4 years.
