Is Huawei's od level determined by the technical interviewer or the supervisor?

Huawei's data in official website shows that od level is a new recruitment model, and personnel relations are linked with companies such as Deco, which is similar to the overseas assignment model. However, from entry to follow-up training and rank promotion, it is dominated by Huawei, and the level is determined by the interviewer.

At present, most of Huawei's social recruitment is od recruitment, and the od model is below 17. Od mode is also a new employment form proposed by Huawei, with grades ranging from 13 to 17, and it belongs to Huawei's reserve talents.
