I was in my final year of college and this was an interview for their graduate programme. By far the worst interview experience I've ever encountered. 1 hour and 45 minutes in total with the majority of it focused on technical questions. When i wasnt sure about an answer the questions piled on. During the interview the senior manager presented a psychometric chart and it turned into a practical exam. It felt like an interview for a senior position rather than a graduate. I wasn't offered a position but even if I did I would have turned it down nowing the type of managers they have interviewing students.
