Halliburton Intern interview questions

Applied when they came to career fair at my university. Got an email asking me to schedule an on-campus interview. The interview was for 30 minutes. The interviewer was nice and asked me a behavioral question, two brain teasers and one technical question. I thought I did fairly well until I ran out of time in writing code for the last technical question

Several phone interviews with employees and final interview with the hiring manager. I think they got my resume from career fair at the university or through online.
