    Average Interview

    Application

    I applied through college or university – interviewed at Yahoo.

    Interview

    It is a two screen process at yahoo. The interviewer's are great and help in case you get stuck. They basically check your programming knowledge and logical concepts. Even if you write the code a bit incorrect, it won't affect your result unless you tell them the correct algorithm. Linked List, Stack , Queue, Arrays and Strings, Searching Sorting and Trees and Graphs are things which should be prepared before the interview.

    Interview Questions

    • Check if the string is balanced. eg {{}} should return true,
      Given a input sentence tokenize it and print the word count. eg the boy went to the school- > the 2, boy 1, went 1, to 1, school 1

    Easy Interview

    Application

    I applied in-person – interviewed at Yahoo.

    Interview

    I had 2 interviews on campus after meeting a recruiter in a job fair. My gpa was actually lower than their standards but they gave me an interview anyways. They asked me resume questions as well as give me an opportunity to explain why my gpa was low (3.4). Afterwords they asked me simple questions like reversing a linked list, and then asked me questions like what other offers do you have? I was then given the 2nd interview immediately afterwards, to which they asked 3 programming questions, like parsing a regular expression given a string, and designing monopoly and how to determine if a list has no duplicates.

    Interview Questions

    • Design Monopoly.
      Given 2 strings, figure out if one is a reg expression of the other.

      examples:
      Y-hoo, Yahoo -True
      Y*o, Yahoo -> True
      **hoo ->Yahoo True
      ya-* -> yahoo True

    Difficult Interview

    Interview

    The interviewer was a male and very polite. First he asked something from my resume such as what is my favorite projects. And then we started the technical questions. The technical questions covered a algorithm problem, a c programming problem, some basic stuff about STL in C++ and some other practical questions such as writing a bash. My performance was very bad.

    Difficult Interview

    Application

    I applied through an employee referral. The process took 2 weeksinterviewed at Yahoo (Sunnyvale, CA) in March 2015.

    Interview

    Two phone calls both technical, asking SQL questions and simple tree traversal questions. Also asked scenario questions and how I would analyze the data and go about solving the problem. About a week later I got an email to be brought on site. They pay for airfare, good, and taxis. Once I got there (on Friday for "Yahoo Days"), I did a coding challenge then talked to three members of the team I was applying for. There was a mixer at the end of the day where you're able to talk with other applicants and some employees. My interview was not technically intensive, but others who were interviewing said there interview was almost all coding questions.

    • Determine whether there is a loop in a linked lisk. Find the head of the loop. The questions are quite easy, and I figure out and write down in 15 minutes. However, the HR did not contact me after the interview.   Answer Question
