IBM Software Developer interview questions

The interviewer were friendly and made me feel comfortable then started with the interview . Asked me questions from the core concepts, then followed by my resume projects . You need to know what you have done in your resume and why you did or opted those.

it was 2 questions for coding. one was on the linked list, which i solved using python. then the next question was based on sliding window concept, to find the max substring in the given string.
