I searched to see what Infosys (1) and TCS (2) actually pay a "Computer Systems Analyst" and found:
- For Infosys, there's only one result for Houston where the salary came out to be ~105K.
- For TCS, it's around 85K-87K for San Franscisco area. Didn't find anything for Los Angeles.
I can't vouch for the correctness of data but the site says they get it from the Department of Labor. Infosys and TCS would probably be using different job titles on their H1B petitions to try and get a lower wage determination.
