It was aptitude test and technical questions..the aptitude test involve English, mathematics,current affairs and basic science. While the technical text involves process questions, It was very interesting because I prepared the the questions very well.. The interview lasted for 1hr 30min for each part

The interview was smooth they will give you ease to answer peacefully. It will be of around 1 hour(depends on HR and Department you are selected in). First 45 min they will ask you technical question based on resume and your job profile laat 15 min they will cover HR question.
