LTM Limited Senior Python Developer interview questions

Interviewer is very bad. The one who takes interview has to be polite and be patient when asking or listening. He asked to write a program, I wrote and it executed successfully. Then asked few technical questions, in the middle of my conversation, when I am explaining he said I am done with the interview. I did not understand what went wrong. He was not at all interested in taking the interview. Please put some interested and talented candidates as interviewers. Don't waste candidates time.
