They asked me about my studies, about my interests,... They told me what would I do if I accept the job and showed me around. They asked me about my English knowledge but I didn't had to demonstrate.

5 rounds, then an offer, which I refused, but agreed to stay in contact. After a while wrote back if still valid, they replied it is. Wrote back that in 1 week time we can continue with process, but holiday season arrived. Then ghosted. Then reestablished contact and miss informed, Finally rejected after some more ghosting, they ghosted me for a month. What looked like a done deal, finally fell through, which I understand, but it took them almost a month to reach a status. Could simply say no and be done with it. Some shady background stuff going on there. Lost almost 2 months with them so would not recommend. Max. 2 interviews with them, don't bother with their shoddy practices.
