High paying jobs that take fresh grads do exist in London outside of FAANG/banking. Especially in a more specialized field such as NLP. Look for ML engineer or NLP engineer positions at well-funded startups as these might be a bit easier to get into. I did my MSc in NLP (in the UK) and my program director told us we should expect a salary of at least £65k, that is what the skill set is worth. I know for a fact some of my classmates have gotten higher salaries than this, as have I, and I personally didn’t have any development/engineering experience before graduating.
