Huawei Technologies Project Manager interview questions

Require to fill in employment form before interviewing. Interviewer came from mainland China, communication was abit of a challenge. Majority of the interview was going through the CV, literary line by line, trying to identify faults in the CV. Before ending, interviewer stated HR will contact me if successful otherwise NO call. I found out my interview was unsuccessful after a week from chasing up with HR. Try to get some feedback from HR but had a difficult time trying to speak the HR. It seems HR never answer his phone, both mobile and desk phone. Very frustrated with the company, poor interviewing process and very unhelpful HR department.
