I’ve heard so many horror stories from Climax...
Every games industry job above a tester will claim it needs industry experience, honestly if they’re not specific about what experience is required (ex: 4 years as a designer, MMO experience, shipped 2 titles), it’s often fluff and you may have success anyway – especially with tangible modification experience. And yeah, if all else fails go in at the bottom and work your way up. I’ve seen testers join towards the end of a project, and move up the ladder quite rapidly. Just realise that you won’t be bumped up automatically, and still need to promote yourself internally (where it’s much easier).
My parents have always been supportive of working in the industry, but if I’d wanted to tarmac drive-ways for a living they’d probably be behind me all the way.
