GDEB flew me to Providence and had me drive to Groton for the interview. My interview only lasted 15 minutes and did not get an offer. Interviewer was borderline rude. Massive waste of my time and the worst interview experience I've ever had. I felt that the interviewer either had no interest in hiring me, thus purposefully wasting my time by having me come to an on-site, or the interviewer immediately did not like me for some personal reason. We never discussed any technical matter.
