ik im late but
always ask at least one question when they ask "Do you have any questions for me?" and as someone else itt said don't ask a question you could find with one google search
if they ask you to give an example of something that happened to you at a previous job, be specific don't be general. tell a specific story, thats how they want you to answer.
If they ask you questions that have nothing to do with the job such as "What are your hobbies" always try to somehow relate it to the job.
ive got more but these are always key
Follow all of the above steps but also slide over a paper containing your KTT2 user @ and tell them this is where they can find further references
