This may be my bias, but the experience you had is explainable.

The former H1B workers probably were in the US as an onsite assignment or through a consultancy/contractor. Most Indian consultancies view people as warm bodies on the chair. Which is why you find people with fewer skills.

The latter workers are most likely people who relocated to the US for education or were hired from India from a US employer because of their skills.
