Hi, As a partner I have been through multiple interviews with JLP and honestly they should be nothing to worry about! Remember the interviews are mainly personality based rather than experience! The group stage will most likely consist of giving you a task which in my cases has been... Develop an event which could be held in store to both drive footfall and develop a relationship with the customer. Put yourself in the customers shoes and be inventive. You will be assessed on how you communicate with your team and include others but also on the actual ideas you have and how you develop them. Just be yourself make friends with your team because they are all in the same boat.
After this task you will have a slight wait and then an individual “interview”
In my case this has been both ...
1) What are my strengths weaknesses, how have I worked as a team, what do I enjoy outside of work, what could I bring to the role.
2) a “sell me a product” task where you are given a leaflet and 10 mins to view the products and then recommend a product to a “customer” based on their requirements. Even if you have no retail experience just be proactive and try your best. After all you have been in to a shop and know the process of a sale!
Good luck and if you have any questions feel free to ask ( I will reply tomorrow )
