Barclays Graduate Engineer Trainee interview questions

Barclays came for Campus Hiring, 1st round was MCQ Round along with 2 Coding Questions. Around 200 People were selected for Technical Interview Round. Although knowing that they are just going to hire barely 15-20 students, After selecting those students took interview or rather say wasted time of around 150+ students just by Asking Introduction and HR based questions in a "Technical Interview". Interviewer was never in a mood to take Interview he just wanted to spend that 30 mins by talking about here and there. Such a bad Interview Experience.
