I applied through college or university. The process took 1 day. I interviewed at Jacobs in Sep 2014
Interview
First an aptitude test was conducted. Questions mostly consisted of Fluid mechanics, Strength of meterials and other basic concepts. Then we had a group discussion round. We had to discuss about a social issue given by them (goverment corruption, affirmative action, teenage suicide). Then those selected in both got to the interview stage.
Group interview discussing the topic of recent engineering news. 8 mins discussion 1 question.
written test was easy with written and calculation questions. Around 6 questions in total, 30 minutes.
Technical Test for an hour, focus on knowledge in engineering, similar to the mid-term test in university, not really difficult. And debate section for 10 mins on the trending controversy.
