There will 3 steps of interview starting with Skype. Basically about how much you know the destinations and your skill to improvise an explanation. After if you pass this step you have to do 2 full day of workshop and will test during that workshop. If you pass you have training and after work. I passed the a Skype calling but won't will at workshop

[I'm still in the selection process so regarding the question below, I don't know if I'll get an offer but I had to choose something] For one office there was an interview with an interviewer while for the other the interview was through a webpage where you read a question and then you record yourself answering it. Your have only one go at recording each question but you get 2 minutes to prepare each question before answering. And then you get a minute to answer it while it's recording you. The questions were very interesting, the right amount of fun and a bit of a challenge. The next step is an online group workshop and then the final round in in-person at the location of the office you applied for.
