Your task is to contact the previous workplace(s), confirm the person’s position and exact dates of employment, and capture any additional remarks the HR or direct supervisor is willing to share about duties performed or overall conduct.

My Android and iOS applications are ready for a full-scale security check and I’m looking for a Certified Ethical Hacker who specialises in mobile VAPT to carry it out.
