Entrevista
Rectruiter contacted me via Linkedin. After a short video call with HR, they sent me a technical exam 13 c++ questions and gave me 2 weeks to complete. I gave almost 25 hours to prepare a nice document with detailed answers. After I sent document, they sent me a rejection mail directly without any feedback. I found this procedure really rude. As a professional company, I would not expect this behavior from WallBox.

Entrevista
Un autentico caos y muy poco feedback por su parte. Poca comunicación entre RRHH y la parte técnica, casi tres semanas esperando para saber algo y resulta que no se comunicaban entre ellos. Una perdida de tiempo
