I applied online. The process took 1 day. I interviewed at Baidu (Beijing, Beijing) in May 2011
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.
Interview questions [4]
Question 1
Describe the difference between HashMap and HashTable
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.
The interviewers were professional, friendly, and made me feel comfortable throughout the process. They tested the basic algorithm ability (leetcode mid).
One aspect I liked was the emphasis on collaboration and communication. The interview felt more like a conversation rather than a strict Q&A
leetcode medium, and some data structure problems about linked lists to test my ability in java. then second round mostly chatting with the team lead about my resume projects and past experience. Very positive interview experience.
I applied online. The process took 1+ week. I interviewed at Baidu (Beijingshan) in Jul 2024
Interview
Good experience and nice interviewer, he really knows well about my cv and what he does, and he focused on my CV and dug very deep into it and asking a lot of related questions.
