Not necessarily. Most clients want to see some form of paid office experience though we understand this is not always a realistic requirement for law students. In saying that if you don’t have practical work experience it might be the case that law firms won’t want to train you. Firms typically hire in greater numbers at the 2+ PQE level than at the 0-2 years PQE level. Supplementing the legal theory taught at University with practical legal training to make you job ready can help you overcome a lack of practical work experience.
If you have no law firm experience but want a law firm job - you should consider Yegal Academy training.
