IBM Security Intelligence Client Executive interview questions

1) Call with recruiter 2) Call with hiring manager 3) call with his mgr 4) stand & deliver presentation. What left bad taste in my mouth was that I invested substantial time in preso. And they kept me on for 1 hour afterward, stating things like "you clearly did your homework." And asking me several questions around when I could start. They committed to providing feedback afterward (which I said was important to me), but recruiter merely gave me a form rejection 3 days later. Felt like a slap in the face.
