Pros

Plenty of opportunities to explore new technologies.
Quality of work, compared to other companies, is better.
Many good processes are followed.

Cons

Work life-Personal life balance is affected.
People slog too much.
Not at all recommended for girls, because management expects them also to stay late.
Some technical leaders are annoyingly dumb, and makes me wonder who the hell recruited them at the first place!
With so many dissatisfied employees, Huawei is facing severe attrition, even from its Tier1 employees.
Attitude of management - people who stay at office more (though not working, but just browsing through mails) are recognized for "excellent" performance.

Advice to Senior Management

Stress more on getting good resources, and try to retain them.
Lay off idiots.
