Whoever disliked this question, stop being so narrow minded - it’s actually a very legitimate question and one that should be discussed given upcoming changes.
This will all change with the SQE - so this is only applicable for the next 15 months. When the SQE comes and replaces the QLTS - there will only be one route to qualification for all people, no matter what their background.
Currently with the QLTS you have to be qualified in your home jurisdiction. You then take a set of exams (which are basically what the SQE is based on) but do not need to gain any qualifying work experience. Once you complete and pass the QLTS you are a qualified lawyer in England and Wales.
This means you don’t need a training contract. However, some firms will allow people who are taking or have passed the QLTS to join on the equivalent of a training contract. However this is typically for people who come in with little experience, and so working for two years on the same rotational basis as a trainee makes sense. Anyone with significant work experience (typically 3 years or more) would be advised to apply for NQ or qualified roles instead - but they would have needed to have passed the QLTS.
However, this all changes with the SQE. Once the SQE comes in, candidates just need a degree (they don’t need to be qualified in their home country), but even if you were qualified elsewhere, you would need to demonstrate 2 years of working on English law (even if that is outside of the U.K.).
