Thankfully my interviewer was much nice and seemed to give me multiple tries, telling me that they might do another one later if I really failed.
Overall the interview process was OK. I guess the only invasive part was when they interviewed my neighbors in person without telling me. (When the FBI comes knocking on your door, you freak out)
I also turned down the internship because the pay was abysmal for IT. $15 an hour.
So the story goes, they only did that because the Defense Investigative Service didn't have anyone who could do the job locally, and so DIS must have asked around to find out who could do the job for them. But DIS agents definitely talked to various friends from college and other neighbors I had over the years.
Apparently only my grandparents got the visit from the Secret Service.
Well, there goes everyone.
But there is no need to make a majority into a universal here.
