Hi Victor!
I am new around here! Nice to hear that there others on the process!
Congrats for continuing on the process!
As per the language test, I do not think that it is a must. I have checked on an interview WFP made a few months ago, about the FIT Pool process, and they did not mention it. You can check that out on the faceebook of WFP, where there is an interview.
I would like to ask you about the video interview. Can you describe the questions you were asked?
Thanks in advance!
Jason
