You'll taking through your CV and experiences, before it all goes sideways.
You'll be asked technical questions about fire investigation, which if you like me read the job description which said 'No prior experience in fire investigation necessary' would come as a bit of a shock.
The questions depend on the discipline of the engineer interviewing you, mine was an electrical engineer and thus I got asked questions related to electrical faults and components - I'm a chemical engineer so had very little knowledge of this.
Overall it was a pretty bad interview and the time from submitting the application to getting an interview was pretty long (3 months).
They tell you there that they like to 'take people out of their comfort zones'. I may be wrong but its a job interview which for most is scary enough without the added discomfort of having to answer questions that are very specific to a particular type of fire investigation.
I read NFPA 921: Guide for Fire and Explosion Investigations cover to cover in preparation for this interview, to gain an awareness of the job, but that did not help in any way as the interviewer treated me like I was an experienced investigator.
If you're experienced, by all means apply for the role but I wouldn't work for an organization that sets you up to fail from interview stage while advertising a role that says 'Requires no experience' and 'Learning and development provided'.
