This might not apply for this particular type of profession, but the Glassdoor website has sample interview questions for some companies but it relies on user submitted data. Alternatively, you could just google for common interview questions as many of those should apply to any type of job interview.
well it's quite stupid because they say that training is offered if you pass the vetting/interview but it doesn't say you need any qualifications so what can i do to actually get the job, can you provide me some questions on what will be said
