toothsi Senior Backend Developer interview questions

1. He asked me a DS question for which I gave and wrote the solution in 7-8 minutes only. 2. Later he asked out some NodeJs and Javascript questions all of which I answered immediately and explained to him well. He wrapped up the interview in 15 min, after taking the slot for 1 hour. It seemed like the engineer was himself not in the mood of taking the interview seriously and it was totally a waste of time for me.
