Knight Capital Senior Java Developer interview questions

Went on this interview through a recruiter. I arrived 10 minutes prior, asked for the hiring manager who they seem to have trouble reaching. Finally they told me to take the elevator up arrived at the IT but door was locked. Someone was nice enough to let me in. No sign of hiring manager. 5 minutes later, he comes and gets me. It did not seem like they interview people much since they did not have a conference room or office available to interview. We finally ended up in an office that was like Arizona in the middle of the Summer. The hiring manager asked about experience and asked some technical questions. From the questions, it was clear that they were using J2EE circa 2001... going from JSP/Servlets to Struts 1.x. From there is was clear this job not for me. A lead developer came in looking sloppy, miserable and gave me a dead fish handshake. This was my first interview in quite some time and used it to bone up on interviewing skills otherwise would have walked out.
