The bigger the company the less impressive "senior" is. There are probably three levels of staff above it and then distinguished super fellow territory.
A senior software engineer can easily make $300-400K+ at BigTech that’s “impressive” enough to me.
On the other hand, a “senior” working at a bank or other large non tech company will probably be making less than $175K if you aren’t working on the west coast.
For instance Delta
Hardly. Senior at Amazon is pretty prestigious. A Senior at Google is also a pretty nice title. In my experience smaller companies are more likely to give out the Senior title like it's nothing.
