Meet Your Principal Interviewers
Two founders, not a platform. We have each built a company, hired its engineers and lived with every hiring decision. Today we bring that experience to your technical interviews, live and human to human.
Our clients are companies across Europe, from the DACH region to the UK. We also interview candidates in the US. We cover all European time zones (Lisbon, London, Vienna, Berlin and Sofia) and US time zones from Pacific to Eastern.
