Long telephonic and video interview. Maths, probability questions and a small programming assignment. Moderate difficult interview level. Motivation/ interest to join cit sec. Started
on time and very efficient use of time
It was mostly about coding. I was first being asked to share my research experience followed by a Q&A, and then we moved on to a DP problem. Since we discussed my research for ~ 40 min, I didn't have time to finish testing my code.
