After many discussions on email, phone and video calls with various people, I received letter of offer. Then was advised of compulsory training, initially as paid arrangement but then changed to unpaid online due to Covid-19. I was ok with all these so far. But then after the training - which I had to take time off current regular work - there was no follow up correspondence. I sent an email to HR within a few days of training completion and no reply was received. I understand that Covid has meant changes to many things, but the discussion/interview/ training process took almost 4 months all up! It would be ethical for them to at least do an update - even if it is just to say "we're sorry but the position is no longer possible due to Covid-19 at the assigned country". What's the point of insisting on training and wasting my time (and their resources) on it? Reading the feedbacks on Glassdoor revealed how unethical this company can be so perhaps this lack of closure from them is to be expected.
