HCLTech Junior Java Developer interview questions

I was contacted by one of the recruiter. It was not very professional from the very start. The recruiter didn't include how the interview will be proceeded, like in person or phone or video call. On the actual interview day, the interviewer who seems to be an engineer, called one hour early, to which I said I am not available yet. So we agreed to do it on the time we agreed before. This time around, the interviewer was late for 30 minutes, and very unprepared, and disorganized. I answered both technical questions correct. The interview ended abrupt because he seemed to have something else to do. 1 week after and nothing. So disorganized to a point I didn't know what just happened lol.
