It started off with an aptitude test. Once you clear that, you will face the interview. The interview is pretty stress-free. There will be a panel of 5-6 people and one out of that will be a subject matter expert (not an employee of the organization). Usually, the interview lasts for 45-60 mins. Once that is done, they won't declare the results then. But communicate it over a course of a week or more than that.
