If the individual was working for the 3rd party company, why was he attending for a job interview with the NHS?

If he had already left the company, why did the interviewer feel the need to send the photo(s)?

Did the 3rd party company really have a CEO and a Quality Manager?

Has the Quality Manager been sacked yet? Or was it him who was being interviewed?

Maybe I've been reading too many Maigret novels.

If you don't inspect ... don't expect.
