Sorry for my late reply. It went well I think. I had quite a few questions including: why ETH, why this programme, where else I have applied, what programming languages do I know, why have I chosen my current bachelor degree, and a short discussion regarding my proposal. However, they told me I am in the short list but unfortunately there is only one scholarship for my programme (CSE) so the decision is quite difficult for them. However, they said the final results will be probably available in about 2 weeks.
