Halliburton (Field Engineer) interview questions

Halliburton came to my university as there was a career day with the students. So, all the students from specific faculties are invited to attend the talk. Right after the talk, there were 2 test conducted, IQ test and also technical test. Both tests were multiple choice question. After that, the HR took some time to review all those tests and the shortlisted candidate were announced. There were 30 of us. Hence, the next day was the interview session with with the HR which lasted for around 20 minutes. I will be informed later whether I was successful to get through that stage. I am still waiting for the call for next stage which will be an interview with the line manager. I was informed that my CV was placed in Halliburton talent bank and will be contacted any time soon.
