e-stone Information Technology interview questions

It was average, but asked technical question tough. they prefer language knowledge through flowcharts " If X + Y = Z but how ?" and if this happen what will be the answer , and why it happen

The interview process was smooth and easy. It started with a quick introduction, followed by a few basic technical and HR questions. The interviewer mainly focused on my background, skills, and final year project. The overall experience was positive and not very difficult.
