PQE stands for ‘Post Qualification Experience’ (or equivalent for legal executives or non-qualified staff). NQ stands for ‘Newly Qualified’ (solicitors).
NB: PQE is often indicated on job roles as a guide and it can be worth applying for roles still where PQE is indicated but does not quite fit your experience levels. However if a firm advertise for a solicitor with 20 years PQE and you have 6 months PQE, the role may not be suitable for you.
QBE stands for ‘Qualified By Experience’ – it is often used with conveyancing executives who have not gained a formal qualification but have many years experience.
