Employers aren't going to be looking at the university you went to when they're deciding to hire you, their decision to hire you will be based entirely on how well you perform in their interview and assessments - they'll mostly be looking for you to provide evidence of your analytical, technical and problem solving skills. They'll also want to know a bit about you as a person, including your communication skills, enthusiasm, willingness to learn, and how well you'd be able to work in a team or cope with difficult situations.
You can expect to be asked to talk about the kinds of projects you've worked on and the kind of experience that has given you, as well as how well you understand the various tools and technologies you've worked with. You'll probably be asked to explain your understanding of various skills/technologies on your CV. There may be a "whiteboard" problem solving session where you're asked to talk through a problem, and possibly a paper test or being asked to sit down with a laptop and complete a task then explain the solution.
a 12-month placement is a really good opportunity to build up a lot of those skills in a real-world environment during your degree - it's a shame that Glasgow doesn't offer this, since a relevant industrial placement can make a huge difference to your graduate employment prospects. A lot of people tend to find that they learn more from their placement than the rest of their degree put together. The placement effectively serves as your first year of experience, so it can often put you in a very strong position compared to graduates with no experience.
Lastly, whatever university you go to, your success is entirely down to you and how much you take advantage of the opportunity of being at university. Going to any university regardless of its prestige doesn't provide any guarantees about your future career; the only way to ensure that you're successful after leaving university is to really make the most of those 3 years. That includes taking advantage of the availability of the lecturers to talk to and ask for help, using the facilities at the university, chasing up any extra study the university suggests you take on, and making sure you always stay on top of your assignments/coursework, attend lectures, push to get the very best degree classification and to make sure you really understand all the material on the course.
