IBM Junior Software Engineer interview questions

General knowledge questions about data structures, operating systems, object-oriented programming, etc. I was interviewed by 3 different people, in a variety of questions in the same interview he took in the two hour area

Arrived and used the intercom to make presence known. After waiting 20 mins past scheduled interview time, a recruiter brought me into the lunch room along with two other candidates. After 15 minutes being shamed by the other candidates with higher education I was brought to a room on another floor to meet the interviewer. Interviewer was friendly and seemed interested in my skillset.
