Envié una solicitud electrónica. El proceso duró 3 semanas. Acudí a una entrevista en Guzik Technical Enterprises (Sofía, ) en jul 2019
Entrevista
First step was very nice logical tasks.
Second one is live coding session.
Third step is additional task involving physics and math knowledge. I did that one offline in few days.
The best interview process I ever had.
