Proofpoint Software Developer Student Worker - Undergraduate interview questions

The company provided misinformation about the graduation expectation and the length of the internship. I had my first technical interview on Monday. On Tuesday morning, they called to inform me that I passed it, and we scheduled an interview for Thursday afternoon. This required me to rearrange my entire schedule to prepare for the interview. On Tuesday noon, they called again to inform me that the graduation expectation has changed to at least 2 years, which doesn't make sense given that the graduation date is July 31, 2024 - less than 7 months from today. My program combines Computer Science and Biology and is scheduled for 3 years, but almost no one, including myself, finishes the program at that time. Most students take at least 3.5 or 4 years to complete it. Then, on Tuesday afternoon, the HR team once again called me to inform me that since my school's official plan is for 3 years, they can't move forward with me
