In person interview
I applied in-person. I interviewed at NHS (Earls Court, England) in Aug 2021
Interview
I applied through a careers fair, duiring this, I had taken part in stage stage interview, not sure why but I was happy with the process, once i completed my first interview i had been asked to go into my second interview then a week or so after, i had a telephone interview which i was then told i had gotten the job.
I applied online and waited 2 weeks to hear back to see an offer for an interview in my email.
It was calm and relaxed, you have nothing to worry about.
