Ellucian Graduate Technical Intern interview questions

The first stage was an online aptitude test that goes on for an hour and has questions based on data structures, network, etc. You have to get a good score to clear this round. The next round was within a week which was a technical online interview with a senior engineer asking about your projects , and asked me to code also. This went on for an hour. They were extremely friendly. In another week they called for the HR interview at the company itself. The manager was extremely polite and friendly. This went on for 1 and a half hour.
