The working environment in Huawei is scary, you are expected to work OT most of the time. OVERTIME.
They do expect you to come and work on WEEKENDS sometimes...when you are near a project deadline.
a new claim policy. They had reduced oversea travel allowance, now its depending on what country you go.

Money is good but you get no life. Do not expect work from 9am - 6pm in Huawei.
I would say 9am to 9pm. and you have to know Mandarin/Chinese well else you gotta have some communications problem.

They do offer high basic salary, but benefits wise, there are none. No specialist, no dental, some may and may not get contractual bonus.

Appreciate your life if you have one, but money is what you want then go for it, but pls be prepared.
If you have a family or married, you wont find yourself suitable here.
