Huawei got their own certification and it has been proven that in Huawei, PMP, CCIE etc is not really important. They simply do not appreciate those with professional certificates. They only need people to get the job done especially your superior that does not see the client, and they only want good news and not bad news. They wouldnt be able to help you with technical escalation.

If you have 6 Years of experience, max if they hire you as internal contract staff, it will only be for Hay Level 15/16.

Anyway, they are short of Datacom staff simply because people with experience just leave after 1-2 years and those with experience joined and could not last long due to culture difference.

I have experience in Telecom & IT company before, so I know those engineers that work on IT Field when they come over to Huawei, they could not stand the pressure as the work nature and expectation is different. If MRO is the one that approach you, chances is you will be thrown into some shitty projects that does not make money. Datacom & Fixed Network Transmission Services is not making money;)
