Anyone Read "Pedigree: How Elite Students Get Elite Jobs"? This book is either going to save my life and make me hate the rest of it.

Here's a really good synopsis on the book:

'Despite merit-based college admissions, equal opportunity employment regulations and the long-held idea that in America, hard work is the key to social mobility, affluent graduates from elite institutions are still often the ones who find the highest-paying entry-level jobs. In her new book, Pedigree: How Elite Students Get Elite Jobs (Princeton University Press), Lauren Rivera, an associate professor of management and organizations at Northwestern University's Kellogg School of Management, aims to find out why.
Rivera sat in on the hiring processes of several prestigious and lucrative employers and interviewed those doing the interviewing, while protecting their anonymity. The employers featured in the book often valued graduates from prestigious colleges (in particular, Ivy League institutions), who were able to participate in "high-status leisure pursuits" outside of the classroom, such as playing lacrosse and squash, and who had prior work experience or internships at peer employers.
Pedigree is a candid look at why top-tier investment banks, consulting firms and law firms make the hiring decisions they do -- and how when firms say they're looking for the "right stuff," they often mean an elusive combination of economic, social and cultural resources that only those from affluent backgrounds possess.'

A little about me:

Last year (sophomore year) I got tons of interviews for banking/corporate finance/big 4/credit rating agency internships and had second round interviews for most. I always get selected to interview because of college athletics, strong grades, and great work experiences. The problem is that I never got an internship offers for any of these programs. Right now I'm aiming at trading/banking roles at BB banks. Also I go to a non-target (semi-target if someone from my school is on the street - which there's a decent amount).

It's evident that I struggle to stand out in my interviews and that there's always someone who they feel is a better fit. In sophomore internship interviews you're only asked to talk about yourself and walk through your resume and then maybe a few behavioral questions if that's not enough. This lead to discussing my high school experience which is completely nontraditional given that I grew up extremely poor and am a minority.[I can PM you more details about my background if you're interested] The only thing I can get people interested in is that I play a major varsity D1 sport but I'm not even good and don't get playing time so it's hard to get people excited about a bench-warmer. I'm not really good at first impression because I'm kind of shy - but when people get to know me they love me and really like having me around given that I open up more around extroverts (same part of the reason why I want to work on wall street - banking/trading)

If you know anything about the book or read a little bit about it you'll find why I had difficultly landing an internship last year - just not being able to connect well enough with my interviewers given my socio-racial economic background. I'm not the typical jock type that they look for that can lighten up a room with his/her presence. I struggle to convey my story sometimes that's something I'll work on. I'm actually articulate when talking about the financial markets and news but I just don't pass the FIT test. It's been eating away at me for the past year. I don't want to not have the rewarding/challenging career I want because they THINK I wouldn't FIT.

Any advice from someone who's read the book or advice on how to convey fit in an interview?

Thanks, any thoughts are appreciated.
