It also depends on specific departments. Theoretically, all examiners come for interviews with clear intentions, which is different from what some small companies call "reserves".

On the one hand, the interviewer (technical level) should be a senior technical expert in what you call "a certain department" from personal experience. Or a "technical expert" related to this position you will be engaged in in in the future.

Huawei's division of labor is more detailed. Even the same department is theoretically divided into many links according to the specific situation.

After the follow-up interview (pay attention to the follow-up interview), I personally think I should be able to enter "Part A", but the specific work may depend on your follow-up training and "defense" after the probation period. The result of the preliminary trial defense will directly affect your subsequent positioning in the whole department.
