Just a waste of time.
They were absolutely no professional leaving me in a limbo for weeks and weeks (2 months) and never answered to my normal and polite requests for a simple feedback. They just disappeared after 2 steps and after I was kind of introduced to a 3rd step already during the 2nd call, the one with the hiring manager that went quite good. Full silence. Then they appeared again out of the blue after 2 months saying that "Although your experience is impressive, the team felt that other candidates were slightly more aligned with what we’re looking for at this stage", the classic bullxxxx...
This unprofessional way of proceeding that shows no respect whatsoever for the candidates needs to end.
