Yes, I would definitely say this is a fake! Click on the below Airbnb link that spells out the list of verified email addresses that we might receive from them (promise this is legit😉)
As mentioned to you in earlier responses this is fake communication and the email you have now have now shared is not an Airbnb one. If you want to work for Airbnb look for jobs advertised on their corporate website @Andriy28
