The whole process started right away with an online interview with basically CTO and (really arrogant) HR lady. It was the weirdest interview I ever had. The HR lady was nearly attacking me with her questions to presumably make an impression on the CTO. (I understood she is and contractor )
After that, I got a quite complex task which took few days to design. I sent an email with my solution, but the only thing I got was an email from the HR Lady saying they will review my work later and get me to know. And they never did.
I got a better offer from another company later. Save your time and apply somewhere else.
