I applied in-person. The process took 2 weeks. I interviewed at Halliburton (Baku, Baku) in Jun 2015
Interview
Friendly Meeting with HR and Engineer representatives. Questions were based on Resume. Try to have a perfect Resume. Technical questions were based on general knowledge of oil and gas industry, particularly in Azerbaijan. Before interview check the website for local and international news on company's business. Also consider preparing soft skill question/answer. HR asked questions, like, describe yourself, weakness and long-term plans.
Good Luck everyone!
