Few limits placed on employees with initiative. Great place if you're a mercenary sales/trader type and just want a Bloomberg terminal and phone and to be left alone. Despite this, co-workers were decent and the a--hole factor was low.
Weak corporate identity and culture, e.g. they could (and did) change the nameplate and nobody noticed or cared.
Advice to Management
Think about a human resources strategy that includes talent acquisition, development and retention so you're best aren't so easily poached away.
I applied through an employee referral. I interviewed at Knight Capital (Jersey City, NJ) in November 2015.
Started with a phone call, then was flown into the Jersey City office for a "Super Day" which consisted of 5 individual interviews. They understand this was a position for undergrads so there were minimal technical questions. Mostly just got to know a few of the guys.
