In-person interview at University, 3 recommendation letters required, CV evaluation, job offer.
I asked for the opportunity of internship in Switzerland to my university professor. I met the Alstom internal contact directly for the interview at my University. We had a brief conversation about the job and the company; he liked me. The hiring process took: 15 days for the positive feedback, 30+ days to obtain the work permit. Contract received via mail at my address. It has been a positive experience.
