I applied online. I interviewed at BIOOO.CZ (Prague) in Mar 2020
Interview
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.
