SAIC Software Data Engineer interview questions

I was contacted about scheduling an interview soon after submitting an application online. Had the interview a week later. The next day I got emails about filling out more information online and 2 days later got an offer. The whole process was very fast. For the interview, there were two interviewers asking basic questions. A lot of 'do you know what xxx is?'. Answered most with 'no' and tried to guess on some. Interviewer was nice and kept saying 'it's ok if you don't know'.
