    Application

    I applied online. The process took 2 weeksinterviewed at Baidu (Beijing, Beijing (China)) in April 2013.

    Interview

    Did two rounds of telephone interview. Each contains some basic technical questions about C++, such as virtual table or things like that, algorithm questions like in-order travel of BST, as well as a design question like large scale file system. It's a little bit difficult for me to came with ideas about this kind of questions. So it did not went well for me. Hope it would be better next time.

    Interview

    First I applied for a test engineer position online, after several days, the recruiter called me to ask me whether I would change my position to search engineer for business search department (the core department of Baidu.com, most deal with algorithm and other challenge works). Then, about two or three days later, they arranged a on site interview for me.
    While the on-site interview, the interviewer is good (but do not smile at all : -)). He asked me some questions about Java multi-thread problems, DB questions, and some basic algorithm programming questions (write a method to convert a string); final question is about big data problem, the main idea of the question is to search some information through about 10G user action log file.
