Cadence Design Systems visited our campus for an internship + PPO offer. They did not have any aptitude or coding round, they screened our resumes and shortlisted 35 students for interviews. I had 3 rounds of Interviews two of them were Technical and one Technical + HR. All rounds were Virtual through Zoom Meetings First Round: First round went for around 25-30 Minutes. They asked me to introduce myself then which technologies I am good at. Then I was asked about some OOP concepts and design patterns. In the end interviewer gave me a situation and asked what I would have done (This was related to automation as the role they offering was QA Engineer). Out of 35, 15 were selected for the next round.
