I’ve had an interview for Hertz and Medway, Medway they did a role play scenario (this is stated on their website, they provide lots of details to what to expect, and there is also a lot of general information online that is very similar to what is actually asked) Hertfordshire had a very brief and simple maths, chemistry and situational judgement section, but honestly pointless worrying about it as they was very basic, and both asked general questions that are also stated on their websites about why pharmacy, what makes you suited for this role, what experience do you have, really all of these questions you should know the answer to if you are applying to pharmacy anyways, there was no crazy unexpected questions asked based on what i experienced
and just to add my Medway interview was with Greenwich so i’m not sure if it would be different if yours is with Kent but i assume it is fairly similar
