A couple of days after filling in the application, they contacted me asking for a phone interview. The interview lasted for 30min and assessed my language knowledge. The interviewer was very nice. The same day they told me I passed to the next phase, where I would have a center assessment in London. They didn't pay for my flight ticket. Before buying my ticket, they postponed the center assessment. After I bought my ticket, they told me they didn't need me to travel because they already "managed to fill the number of positions". It was very disappointing. It was a waste of money, and time.
