I joined through the process of campus recruitment. It consists of 5 steps; 3-min interview, aptitude test, FGD, HR interview, and user interview. The first step is to actually assess your English proficiency level. Aptitude test consists of psychological test, math and physics. The issue in FGD can be various, but the most important thing is to be actively engage in the discussion, be active! HR interview is a one-on-one interview held in a garden (it was actually very pleasant!). And lastly user interview.
