Hi. Here is my advice:
Wear a smart top and have good lighting.
Check your camera and microphone work beforehand.
A plain back ground is best.
Log in at least 5 mins before to get settled and they will admit you when ready.
Prepare answer in advance to what is likely to be their opening question, "tell me why you are a good fit for the job". You can smash this, do a great job of it and it'll up your confidence for the rest of the interview.
Google the SEAT method to help you structure your answer..Skills, Experience, Achievement and Type of person (I think!).
They may ask you about nhs values, and what it means to you. Having an example of how you demonstrate one or more of them in your work would be great.
I'd recommend using the STAR method to prep your answers to the key competencies listed in the job role (I'm guessing prioritisation, communication, teamworking, confidentiality and customer service??). The STAR method is to describe the Situation, what was the Task, what where your Actions (this is where most content goes) and what was the Result. Tell it like a short story of when this happened...
Final tip, i believe it's okay to say you've made your notes and you may want to refer to them. They will be looking at their notes and it's real life to have notes in the workplace isn't it! Also shows you've prepped. Just dont do it for every question.
Oh and, think of your questions to ask at the end, they are very important too.
Best of luck. Do your prep and it will stand you in good stead. Sounds like you have experience to call on which is great.
At the end of the day, it's a meeting isn't it and if it doesn't go well,there will be other opportunities. Do your prep and you'll be fine tho.
There is lots of advice on YouTube, with model answers to help you structure your answers with YOUR experiences.
I know interviews can be daunting but prep really will help you.
Good luck!
