Halliburton is quite like fella Schlumberger, an oil-service company that merely hires software developers. But Halliburton is not totally like his fella Schlumberger, they do not appear on Rice University's career expo. And they bring in info-sessions, as well as on-campus interview. Purely bluff, like fella Schlumberger. Purely non-technical questions, like fella Schlumberger. And you never know why you are ignore, why you are approached. I am in the first kind. One of my friend received an onsite invitation email, the email tells the date to go onsite, but without a time, a location. And the date has passed, quiet.
