Texas-based firm, which reported revenues of $16bn in 2016, posts ad offering full-time roles on unpaid work experience scheme
Oil industry company Halliburton has been branded “obscene” for advertising unpaid UK internships, which critics say give an unfair advantage to people from privileged backgrounds.
In an advert on its recruitment site, Halliburton said it was seeking “people who want to innovate, achieve, grow and lead” for student internships at its office in Chiswick, west London.
