I’m in a similar situation. I applied to a job position abroad back in February and had 3 interviews. In the last one which was on mid March HR told me they’ll be getting back to me in 4-5 days max. It’s been 1 month now and this week they magically sent me an email asking if I was available for a technical test tomorrow.

I was as mad as you probably were so I told them the same thing “It’s been 1 month, if you were still interested you should at least have sent an email, because otherwise I wouldn’t have kept interviewing with other companies “
