Hey Jacosi! Thanks for this. Were you able to find out what the calls are meant for ?
According to what they said to me, it seems that it is just an informal conversation in order to know the applicant and I guess also to prove your English level.
Thanks Jacosi, that's very helpful! Any idea how long these calls last or what they expect from you?
Around 15 minutes. It seems as a kind of formality before sending their decision.
