I've heard very god things about that university, no negatives, either. I didn't study there so I can't give data or examples but from what I have read employment rates are good!
The most important thing to consider, is the quality of the students who are applying to the jobs. A lot of the time, someone from Newcastle is more likely to get the job over someone form LJMU simply because they have a better aptitude for academic pursuits and can be more assertive. Your typical UCL student stands a better chance of getting a job over the typical LJMU student, because the UCL student is likely to have done so much more during their time and has done more to stand out. It isn't always about the name of your university holding you back, sure having a good university on your CV is helpful, but better universities attract brighter and more successful students, so don't be surprised if they get the jobs first.
Focus on improving yourself, rather than worrying on your university's place in the rankings. Being outgoing, confident, assertive, and charming will take you a lot further than the name of your university. Think of the quiet bookworm doing business management at Durham, vs the social, friendly people person doing business management at LJMU, who do you think would do better managing a team or organising a project? I'd put money on the one with the personality. Conversely, if you compete against someone from a better uni who is also bright and articulate, confident and assertive then of course going to a top 25 uni is better than not having gone to one.
Hope that helps.
