Extremely long and time consuming, lead to nothing.
I am an experienced translator and I was submitted a translation test first and a proofreading test shortly after. The tests were both very long, but I have translated way more complicated texts and sure to have done a decent job. Instructions were super unclear and when I asked more information they just denied it. Don't waste your time.

Question 1
They expect you to know how to translate in various language combinations, have a degree, have PM experience, be familiar with different kind of coding, know how to use CAT tools and offer a very little salary for all of these requirements.
