Other comments

Interviewer was a great leaning experience.
The key to cracking an interview is being 100% true. Not saying terms and words you don't know ( avoid them at all times) and thinking thrice before speaking an answer , because the next question might very well be based on this answer .. Don't feel bad if you don't know an answer be true and tell .
