What people at Baidu say
Reviews originally posted on Glassdoor.
Great work environment, more opportunities to be exposed to advanced technology
Working pressure was not so heavy, and there was not too much over-time working. This was very precious among the internet companies. The pay was average, not too much either among others.
Open space work area Many ways to evolve and build your career Diverse projects
Some department's manager is cool, support your career life. But some department like 'Baidu Mobile App Dept. ' is becoming busy and busy these years, higher executives can't find the way forward and PRD's are unclear, without clear thinking.
Baidu is a growing company, if you are lucky working on a hot product which can make contributions to the growth and profits of the company, you will have the chance to get promotion very quickly
