You did a PhD didn't you?
You spent 4 or 5 years solving unreasonably difficult mathematical conundrums, wrote your own operating system to control a particle accelerator of a fundamentally new and more powerful type using a household fridge to cool the new high temperature superconductor material you extracted from minerals they you won in single combat in a cage fight with an 8 feet high alien. Not only did you use it to discover the higgs Boson, but you keep one as a pet and you've not only house trained the Higgs Boson, but made it play dead and fetch your newspaper.
Did you? Did you really? Or did you work in Starbucks, and perform outstanding work in customer relations and hygiene management?
How would I know? A stupidly high % of the CVs waste stupidly large %'s of the space on dross like summer jobs. It is actually quite common for a description of something like the complexity of the local bar's stock control system to take up more space than your PhD. About 10% of the PhD CVs I get don't describe the PhD as far as bothering to tell me the title.
OK,I am just a fat ignorant old pimp, so my ability to evaluate just exactly how ground breaking your research might be is finite.
But I've got to sell you to some bank, hedge fund, software house, consultancy, prop shop or insurance outfit.
So imagine how the conversation is going to run:
Client: "Hey Dominic, got any good newbies?"
Dominic: "Yes, like this guy, he's got a PhD"
Client: "In what?"
Dominic: "Physics"
Client: "What sort of Physics?"
Dominic: "Really hard physics, you know tough ones, big physics, miles long, really hard, you know like physics"
Client: "Solid state?"
Dominic "Could be, this is a smart guy, I'd expect really solid work"
Client: "Can he program?"
Dominic: "Of course, all kids learn to program these days, don't they? Did I mention he has a PhD in physics?"
Guess how likely you are to get the job? Guess how much I am going to get paid for all this?
Mention your summer jobs if you must, but make sure that you describe your PhD enough that we can see how you would be useful in finance.
