A very long interview, the whole process can take more than 1 month.
Minus:
2 interviews with HR and a technical specialist may take approximately 2 weeks. But there is also a test task that can take a minimum of 2 weeks+ and without any payment.
Plus:
It's not all bad, I really enjoyed talking with their senior level designer, he taught me a lot of useful things and helped me understand a lot.
As a result, I can say that it is better to pay for such 2-week assignments, otherwise I didn’t really want to spend so much time without payment.
