Yahoo Interview Questions

About Yahoo

Yahoo! began its journey at Stanford University. Jerry Yang and David Filo, both Electrical Engineering graduate students at the time, launched it in January 1994 with a website called "Jerry and David's Guide to the World Wide Web."

Rather than a searchable index of content, the Guide was a directory of other websites structured in a hierarchy. Jerry and David's Guide to the World Wide Web was renamed "Yahoo!" in April 1994. The word "YAHOO" is an acronym for "Yet Another Hierarchically Organized Oracle" or "Yet Another Hierarchical Officious Oracle." On January 18, 1995, the yahoo.com domain was launched.

Yahoo Inc. is a multinational corporation headquartered in California, United States. It is well recognized for the following:

Yahoo! Search search engine
Online mapping.
Video sharing.
Other related applications.

At Yahoo, there is a mentality of "work hard, play hard." The company promotes teamwork by providing video games and foosball, as well as throwing company parties to celebrate achievements and milestones.

Tips for Yahoo Interview Preparation

If you are applying for senior level roles, you are expected to have a strong understanding of System Design. So practise a lot on System Design questions before appearing for the interview.
For entry level roles, CS Fundamentals and theoretical questions related to Operating Systems, Computer Networks and Database Management Systems are important as well. Make sure that you revise these concepts well before appearing for the interview.
Prepare a short and attractive resume. The length of the resume should generally be in 1 to 2 pages. Try to keep the resume as real as possible and do not include any topic/project on which you are not that confident. It can have a negative effect on the interview.
Be calm and if you do not know the answer to a particular question, do not worry. Interviewers do give hints when you get stuck and you can still make it. Sometimes the interviewer is more interested in the approach to a problem rather than the problem itself.
