so I'm not too sure what you mean by "jobs" (an outsourced job or in-house job?)
- not having any formal studies/qualifications in translation would be appropiate to undertake this course?
The university would be in the best position to decide that. Do you meet the admission requirements? If so, it would likely be appropriate. They would suit such requirements to the projected course content.
- will it be recognized in the translator industry? So to speak, assuming that I obtain a MA qualification, is that enough to start applying for jobs?
Certainly. Successful translators have started and gone on with less. Once again, your fulfilment (or lack of it) of the admission requirements would be an index of what you may expect, and what you may have to brush up on.
- should I get the Dip Trans (IoL) as well?
That wouldn't do any harm. But once again, assess where you are, and when it would be timely for you to do it, granted you're going to do it.
Hope it helps. Others may have more specific advice.
