OpenText interview questions in Bangalore Rural

Its an on campus internship. 1st round has DSA - 2 easy questions on "strings and arrays", and about 12 mcqs which focused on Machine learning and Deep learning . 2nd round was technical round my interviewer was a senior developer (i think), he kept asking me more and more deeper questions. typically the interview would go for 30-40 minutes but for me it went till an "Hour". he grinded me on my resume, my projects, even asked me to draw the System architecture of my project, at a point i started thinking if this is for an Internship or a 20LPA Role.
