World Wide Technology Senior Applications Integration Developer Web Methods interview questions

The hiring manager was fairly nice; gave a good overview of the company and how his group fit into it. The tech lead guy was not nice; almost combative in the interview. Asked me about my experience, especially with Java, integration engines, Oracle, BizTalk. Seemed like this guy was asking 'gotcha' questions and trying to attack skills and experience on my resume. I didn't see a good fit.
