LR's headquarters should be in Beijing, and DNV's is unclear, but all the offices in Dalian, that is, the ship inspection, have contacted a China surveyor of LR and DNV, one of whom has worked as a maritime teacher, and the other has worked in Dalian shipbuilding for ten years and studied painting in Europe, indicating that LR and DNV like experienced people;
As for the fresh graduates, I also asked some time ago. At present, DNV recruits very few people, and LR is unknown. DNV mainly recruits graduate students to review drawings. Dalian office will recruit undergraduates and will independently inspect ships with two or three old surveyors, which also shows that DNV needs talents with strong learning ability;
Other professional background, English level and so on, don't bother.
