I had an HR interview then I have been assigned a project to do at home then send it back and the final step was a video call software engineering interview. I did very well in all and was happy to receive that I got accepted and they will send me a formal offer soon but then I was disappointed that they sent me an email that they will no longer proceed with my visa.
