Written Test: Consisted of 50% simple aptitude (time-work, probability, permutations and combinations, logical reasoning, etc.) and 50% simple metallurgical questions, mostly basics and a few related to thin films. (What are the processes: CVD, sputtering? About characterization techniques: Mostly SEM, etc. One question was: the equation for Gibbs phase rule).

Technical Interview: Lasted about 30 minutes (Technical + HR).

HR Interview: Lasted about 30 minutes (purely HR).

Mostly for the position available, they required someone who is acquainted with some coding/MATLAB, as well as has worked on the preparation/characterization of thin films. They asked whether I was familiar with MATLAB/C++, checked my background (schooling and college). Some technical questions related to semiconducting properties, and mostly why I was focusing on getting into core companies rather than joining elsewhere.
