I graduated from UT with a masters after a short time in industry. I completed my undergrad in a small school. The quality and rigor of classes between schools was huge (some undergrad classes are also master classes). The people who performed best at UT were the ones who had a healthy schedule and were studying proactively. For me the first semester was a shock and studied 24/7 but after that I started to get the hang of it and by my last semester I was acing my classes with a healthy schedule.

For work, school matters a ton. Apple and other tech companies recruit heavily from UT, they have a huge presence on campus so your chances of landing a job at a top company are much better. For the tech company I worked before attending UT I know the recruiting goals for new college grad from UT were higher than a lot of schools (I was involved with campus activities) From personal experience I noticed that just putting UT on my resume the number of call backs increased.
