Pre-employment Vetting in Valparaíso, Chile

I'm seeking a professional background verification service for pre-employment vetting in Valparaíso, Chile. The checks will include:

- Criminal Record Check: This should encompass local, national, and where applicable, international records.
- Employment History Verification: Please confirm the applicant's previous job roles, durations, and reasons for leaving.
- Educational Qualifications Verification: This should validate the degrees, diplomas and certifications claimed by the applicant.

Additional Checks: While not mandatory, these could provide valuable insights:
- Reference Checks: Contacting the applicant's provided references to gauge their reliability would be beneficial.
- Drug Testing: Please advise on the possibility and legality of this in the context of pre-employment checks in Chile.

Ideal candidates for this project should have:
- Proven experience in conducting thorough pre-employment vetting
- Strong understanding of local laws and regulations in Valparaíso, Chile
- Excellent communication skills for liaising with previous employers and educational institutions.

Please note, this is not a single job but a series of checks that will need to be conducted on multiple candidates over a period of time.
