    I interviewed online. The process took a day - interviewed at Baidu in May 2011.

    Interview Details

    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.

    Interview Questions
    • Describe the difference between HashMap and HashTable   View Answer
    • What is index, and describe the benefit of index; MySQL only has prefix index, so how to build a suffix index for MySQL   View Answer
    • Write a method to convert a given string to opposite order, for example, given "abc", then output should be "cba"   View Answer
    • Given a 10G user action log file, and each each in the log is userID-actionID format, also give you a PC with 4G memory, find a way to search for those userIDs that has at least three action records.   View Answer
