I applied through university. I interviewed at Halliburton
Interview
On-campus recruitment. Numerical and English test, then shortlisted for FGD, then shortlisted for user interviews based on product line that was interested during the FGD session. Then MCU and offering.
I applied through a recruiter. The process took 3 weeks. I interviewed at Halliburton (Singapore) in Jan 2013
Interview
takes about 3 weeks from interview to receive offer. Recruiter not friendly, forcing us to receive the offer. Since I really need a job, i receive the offer.
It was almost 12 years back though, i couldnt remember much details about the interview.
Two rounds interview with different team leaders. Each round have 2 interviewers. The Offer call straight after interview, their decision very fast, will need to respond if you accept the offer within 1 week.
Multiple people from the field and the HR (3 people) interviewed me. They asked question about my CV about me personally and evaluated me as a whole. Do need feel pressure, stay confident and calm nothing asked technical much.
