Entrevista
The interview process at Upstream Security was really smooth and well-organized. It started with a quick HR call, then a short chat with the team lead, and finally a one-hour coding interview. Everyone I spoke with was professional and easy to talk to. They got back to me quickly, letting me know they decided to move forward with another candidate who had a bit more relevant experience.
