You get called at their headquarters where you have an interview mainly from your CV. The questions where about how you completed some projects, what challenges you faced in them, and a few techinical questions (easy but if you havent used the techonology they are easy to forget). The experience was very positive and the mood of the interview very friendly. The only issue is that when i got the offer i had to reply within 1 day, which was kinda stressfull. Other than that an amazing exprience and a fast procedure got an offer within 10 working days.
