I applied online. The process took 3 days. I interviewed at BT Group (Belfast, Northern Ireland) in Oct 2017
Interview
Interview was very rushed and the interviewer was very dull and sounded very unenthusiastic about the whole process. I had prepared multiple answers for each and every question using the STAR interview technique and also had recommendation from an employee already working for the company. However during my questions the interviewer cut the interview much shorter than normal and said I will hear from them shortly. A few days later received an email saying I was unsuccessful. I was disappointed not because of the end result but because of the person on the other end of the interview was extremely negative about the whole situation right away and without any warning decided to end the interview.
