30 minute interview with hiring manager. Basically just went over items on my resume and discussed potential projects at Halliburton as well as company values. Overall, very easy to talk to and a lot of insight gained.
Simple, 1 interview, mostly behavioral asked a couple of basic Python questions. Mostly went through my experiences and resume, asked some high-level technical questions based on my background. Interviewer was easy-going, talked about the company and work to be expected during the internship.
