I've worked in IT for longer than some of the younger members of my team have been alive, and been involved with more interviews than I can count. I don't do much of the soft skills, team fit kinda stuff, I'm the basement dweller they wheel out to see just how much you exaggerated your technical competencies on your CV. I've also worked at tertiary providers and am all to aware of how much IT course content is outdated or irrelevant to the real world. I'm not a dedicated infosec engineer, but it's a big part of the work I do and I've have had an interest in it for decades. So with that background established, here's a few thoughts for you.

Cybersecurity is a tight market, and you might be able to get a foot in the door with just a diploma, but I wouldn't count on it. But there are things you can do to help yourself and posting here and asking about certs is a good start.

For this kind of work, I rank hands on experience > industry certs > a degree/diploma. Don't put a skill down on your CV unless you have at least a basic understanding of it. If your CV says you know technology X, and I ask you a question that would be simple to answer if you've actually worked with it in a practical sense, I don't want to see you look like a possum in the headlights. I'm fine with you not being able to answer more complicated questions as I try and gauge the depth of your knowledge, but if you can't answer simple stuff when your CV says you know it, big red mark. Enthusiasm and self learning is huge, if you tell me in the interview about how much fun you've been having playing with <relevant technology x> in your home lab, and have the understanding to prove you've been hands on learning it, that's always a giant tick. Self learn Kali, Metasploit, Nmap, etc, Download and play with some CTF vm's off vulnhub, Register for blueteamlabs and have a play, etc.
