Digit Insurance Java Lead Engineer interview questions

First-round - 30 mins Video interview where the interviewer can see you but you can't see them. For a Java-Lead-Profile, I was expecting more end-to-end application questions(maybe I am wrong). But he was focussed on "what is this, what is that in java" Moreover, the interviewer was travelling while conducting the interview and reached home in between. He was focussing on the definitions(I could hear background noise and he was distracted initially). He was rude, unprofessional and disconnected the call abruptly. My worst interview experience so far, in my close to 9 years of industry experience.
