I applied through a recruiter. I interviewed at Directi (Bengaluru) in Jan 2019
Interview
Good. Get your basics right. There aren't any specific topics. Better to have a grasp on Algorithms and Data structures. Also need to know time and space complexity. Pick only programming language you are most comfortable with.
It was great, the questions were difficult and you need to explain full logic. They won't accept a partial solution. Overall the interview was difficult. You need to prepare for it beforehand.
I applied through university. The process took 2 days. I interviewed at Directi (New Delhi) in Dec 2017
Interview
Very unprofessional. It seemed as if they were there only to make fun and humiliate students, especially the ones from non-CS background. Multiple rounds but still no offer to any student.
