Linguist Testimonial

I’ve been working with cApStAn since 2012. It was an amazing moment when they found me for one of their projects because I was still a novice, so to speak, back then in the translation industry. But they’ve been patiently working with me to the point that the working relationship has become so precious. I say, through my experience, that cApStAn see and trust in your potential, build you up in your skills and help accomplish something truly satisfactory. They never lose friendly spirit to communicate with you and their promptness to support you is amazing. And as a matter of course, they are indeed professional in every aspect of their jobs. I certainly recommend cApStAn to anyone who wants to find enjoyment in their work.

From the very first moment I met the cApStAn team back in 2008, I thought it would be great to collaborate with them…and it was such indeed! The professionalism with which they manage every single (international) project is their landmark; the passion and enthusiasm they put into their work are always perceived. They are always there if any queries should arise during the job and they are open to comments and suggestions. All these characteristics put together have made me love working for them. Absolutely…yes!

I have been in translation industry for more than 16 years and have been in relation with cApStAn and its sister company, BranTra, for nearly a decade now. I cannot think of another agency on a par with them in terms of fair remuneration, project support and responsiveness, interesting projects, clear instructions and quality control standards (after all, linguistic quality control is what cApStAn is internationally renowned for). The Project Managers are always there to support and treat you in a professional and friendly manner which stems from the company’s excellent, humane culture and team spirit.

I’ve been working with cApStAn for about 3-4 years. The jobs are very interesting and I see them as having the greatest impact/value for the society among the projects I participate in as a linguist.

I prefer working based on such principles, and cApStAn always championed in this in my eyes since we have started our cooperation.
