I applied online. I interviewed at Revolut in Oct 2024
Interview
Primero tuve un test técnico automatizado. Después el proceso continuó con una entrevista con Recursos Humanos que me pareció que la persona que me lo hizo no se había leido la descripción del puesto. Para terminar, tuve otra entrevista con el que iba a ser mi responsable y aquí me descartaron.

Interview
A entrevista foi excessivamente técnica e impessoal, com pouca abertura ao diálogo. O entrevistador mencionou ter apenas 15 minutos, o que transmitiu pressa e dificultou uma troca mais equilibrada e informativa.

Interview
This interview process was disappointing and felt poorly handled overall. I received an initial email inviting me to complete a technical task via HackerRank. The documentation provided clearly outlined which coding language and exercises applied to the role I had applied for, and which applied to a different engineering role. However, the actual HackerRank test I was assigned corresponded to the other role, not the one referenced in the invitation.
I went ahead and completed the task anyway, as I had some familiarity with the language. After submitting it, I tried contacting the recruiter multiple times, but despite three follow-up emails over two weeks, I never received a response. A few weeks later, I was notified that the role had already been filled.
The lack of communication and personal consideration made the experience feel impersonal and disconnected. Given the time candidates are asked to invest, even if it’s only a couple of hours, clearer expectations and basic follow-up would go a long way toward creating a more respectful interview process.
