Interview happened the day after career fair, in a booth inside our school. Interview was very informal, asking about logic questions. I heard some of my friends got questions about actual cs problems, but at least when I interviewed with Karl Chan I got logical problems and it only lasted for 30 minutes. And I did not get an offer response (rejection or acceptance) until I send them an email, and what I got was automated message. I am curious whether this unprofessional company will be able to distinguish between candidates at all.
