    Software Engineer Interview

    Interview Details

    I get the interview on the career fair. The interview is on campus. The interviewer is helpful. He asks me to write some codes directly after I get in the room. Just like general code interviews. He does not ask questions on my background. The question is not hard. But I debug for a long time before I find my problem. I am not good at writing code when someone sit aside me.

    Interview Details

    Submitted resume on career site. Got on campus interview call. Interviewer was friendly, but was not open to solutions in languages other than C. I got the logic correct but messed up with pointers. Having a grip on pointers is important. Questions were easy but should be in C, I am not in touch with C.

    • 1) Check whether linked list has a loop
      2) Remove duplicates from a linked list.

    Interview Questions
    • The questions they ask were straight forward. They first ask some concept questions about different data structure. What is the difference between vector and linked list? And then they asked me what did two functions do(the two functions did the same job and he showed this two on his terminal), which one is faster. The time function was already there, just call it.   Answer Question
