Interview Stories
UPDATE: SERIOUSLY GOT A JOB BECAUSE OF THIS! Went to an interview. Interviewer: 'Write an example of closure.' Me: *Writes the example*. Interviewer: 'Namaste JavaScript? 🤔' Me: '😐'. Interviewer: 'Even I had the same example in mind!' We high-fived each other. Happily working ever after! 🧱
I was explaining Hoisting with a demo. Suddenly the interviewer said, 'You watched Namaste JavaScript videos, right?' I said yes. He said, 'OK, let's move to the next question. Your concept is clear. I study from there too!' You're trending, sir! 🚀
I had a JS interview a while ago and noticed most questions were straight from your series. This series is amazing; I've never felt JavaScript like this before! ✨
