LTIMindtree 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.
