Yeah, the pay disparity is unbelievable.
I know two people that work in the same location. Both are IC4s.
One makes around $100k total compensation with no RSUs and bonus - has been at the company for more than 20 years.
The other makes $380k total compensation with almost $200k base - joined the company two years ago.
Now, an IC-1 was hired two years ago as well at the same location, with a base salary of $120k and a total compensation of $175k.
There is a huge pay disparity -- not sure if this is typical at other companies. But I am sure the gap is not this wide at other companies.
