For someone who works in finance, you should understand that the market for software engineers in Switzerland simply doesn't pay this kind of money. The average salary of an ETHZ new grad is 80-85k CHF. You can be the top of your class from MIT or whatnot, companies aren't going to triple their entry-level range to hire someone with zero experience, just because they put a lot of effort through university.

I know top 1% students from ETHZ and EPFL who then did PhDs and postdocs under world class professors. They'll probably never get close to 250k if they stay in Switzerland. Even after 20 years on the job.
