I think I would employ a private investigator if I had any reason or special circumstances. But in my opinion, in Spain the most common cases to employ a private investigator are infidelities in divorce process and working frauds. For example, some employers hire the services of a private investigator to know if a worker suffers an illness and if he can really work or not.
I like so much mystery and detective stories but I don’t know if I would like to work as a private investigator. Anyway, I think it’s not an easy job because there are a lot of dangerous situations.
I haven’t had strange or really interesting jobs, when I was student I worked as a teacher of small children and as a shop assistant. And when I finished my university studies I started working in different law firms, and finally last year I passed the official exams to the public administration.
