Actual facts I would like to share.
I am a certified translator working freelance since the last few years, and as of today, it is 4 years since Mars Translation and I started our professional collaboration. As a freelancer, I have the possibility to work with as many companies as I wish, and my experience with Mars is, in two words, completely solid. They were not recruiting, I emailed them my CV and a cover letter and a PM contacted me, filled me in with the onboarding procedure which included not only submitting my documentation but also taking practice tests in the fields of my choice. I took them, got a pass in most of my chosen fields and a fail in one of them, and PMs started contacting me to assign me work. Over the course of the last four years, my workflow has grown steadily, I moved up their internal ranks for linguists and at present my workflow with the company is such that it has become my favorite company to work with. They are well organized and communication is precise and clear. If I feel I need to report anything, I can always contact the corresponding manager to assist with a solution. Payment-wise, I have no complaints whatsoever. They are thorough and swift to make sure I get my payment on time and that is something I treasure for obvious reasons. I absolutely recommend freelance linguists to apply and give their best because this is one serious company to work with, and for people needing linguistic services, give the company a try and you will not regret it.
