The school isnt top tier..but it is fine..yes grades help. You are on the right track for sure!
here is the key...you have to meet people, the right people. ill give you my story:
I went to Texas A&M...decent school...but there are better. when i graduated the business school was ranked in the Top 20. My GPA? 2.2. (despite a 138 IQ) not kidding. the lowest GPA of anyone i know that actually finished. I happened to be very bad at sitting on my duff listening to people talk. to this day i swaer i will NEVER go back to school..i truly despise it. So it has been a real uphill battle for me..overcoming bad grades. I even graduated late (the 6 year plan) at 24. I am now 30.
..strangely enough, I have a stronger grasp on economics, finance, and languages than most people i know...i just am not good at school...i taught myself pretty much everything...AFTER i graduated. wierd huh? i am even fluent in Spanish now..upon graduation i didnt even know what "cerveza" meant.
Upon graduation i became a reatail broker (in 2000...bad idea) and bounced around a bit. One year I wound up at a head hunting firm...this was a real break...i found out how to REALLY get people on the phone (as a broker i was too intimidated), and how to write a resume.
From there i learned a few key items:
1. If you want a job, talk to the boss. period. Get him on the phone. he is the decision maker...HE will get you the job. not HR, not a website, not a recuruiter...YOU and HIM.
2. Learn how to write a friggin resume..correctly. only put GOOD info on it. everyone had done something crappy in their career... dont advertise that. make it short, sweet, easy to read quickly.
3. People are generally nice...and like to do favors. If you ask..often times they will say yes. so if you want to work at an IB..get the boss on the phone, offer to buy him lunch just to ask how to get to where he is. half the time they will say yes. people like to help people. it makes them feel good.
4. Be likeable. nobody likes an ass, period. Be calm, kind, generous, and forgiving. people will like to be around you as a result...and they will like to work with you.
5. you wont get what you dont ask for. ex "I would like to work for your firm, what would be a good place for me to start?" in the 50% chance they say they dont have anything "who are some of your contacts or competition you could refer me to?". Ask these questions a few times...you will be on the right road.
those are key. If you truly understand this...you can take it from here...but some people need a bit more coaching.
In my case, I am now sitting in tropical paradise running an interdealer market (i am not in the US). I just recieved 2 offers from banks to run their new international funds that they are starting, my inbox has emails from wall street CEOs about some of the deals we are doing...and i have zero debt. House is paid for, cars are paid for, and I dont owe anyone a dime. Not to mention i have a very hot wife (#1,3,4,5 apply here as well).
sounds like BS...i know. But no, i am not rich...not yet...but i was up $1500 today!
Life is good. But it is good becuse I make it happen. I make it happen with those first 5 steps. You should have a decent background (you need to sell something), but I think these are the big difference between the people that make it...and dont. Not grades, not the school you went to.
good luck. you will do great.
