My YLP interview experience was as follows.
The interview panel consisted of 2 persons, and the interview was more or less a stress interview, as I entered the room, the first question was shot even before i could sit:
Me : May I come in sir?
Interviewer 1 : Come in and before you sit down, i was going through your essays, and you have written that you had formed the this society in your college, tell me about it.
Interviewer 1 : There is this another project you have mentioned in your resume, give me a concise description of how you did this and what exactly did you do.
Interviewer 2 : (interjected in the middle of my description) What was the outcome of your project?

Interviewer 2 : What was the outcome?
Interviewer 2 : What are your plans after completing your Engineering?
Interviewer 2 : Give me the specific details of what sub sector in the sector you have mentioned.
Interviewer 2 : Give me names of some companies that deal in this sector.

Interviewer 1 : Why exactly is this sector lagging behind?
