Mindera Backend Developer interview questions

Standard Interview between two "seniors" of the company and myself, using skype. Both completely unprepared to what they would question me about, since most of time they would mute the microphone and talk between themselves , just to get their bearings and actually ask questions, relevant ones regarding the position. While it was said by the HR department than no coding would take place, there was a live coding exercise in a "ide" like hackerrank , simple exercise. However, most of the interview it would be mic mute from the so called seniors and a laughing session , a mocking of the person they were interviewing , since they came unprepared to the interview. A vacancy for java backend, only OOP programming was aborded , the rest, forgotten, since they we really not very well at ease with the interview, they just needed some time to giggle and make fun of the people in front of them. Finally, the final question was regarding the most recent article that I read, didnt matter what (?).
