Interview

Had two interviews and one telephone interview, all of which went fine. Standard interview process with competency based questions. Position expectations were well defined, however, the interviewers were different than those communicated via email. Four weeks on, disappointingly no feedback or response, despite an email requesting for an update from the recruiter.

Fui convocado para uma entrevista, que foi quase toda em inglês.

No final foi dito que me dariam um retorno na semana seguinte, mas não mandaram nem um email automático.

Interview

I scheduled an interview twice, because the interviewer missed the first one. After I talked about my experience he just basically said ‘Bye’ and hang up without giving any description about the role. Very bad experience. Got no response at all.
