Worst company I have ever interviewed for - Senior Developer VISEO Employee Review

I had the opportunity to interview with this company and was offered the position. However, from the very first day, it was clear that the domain they interviewed me for did not have an existing project, and they intended to expand into that area. Just a mere seven days before my scheduled joining date, they informed me that there would be a delay in my start date. Despite sending them three emails regarding my visa status and other necessary processes, they did not bother to acknowledge or respond to any of them. I even reached out to the Manager, with whom I had been in frequent contact, through text, but received no reply. Eventually, I had to insist on a meeting, during which they disclosed that they currently lacked a project and were uncertain about my joining. I am bewildered by their unprofessional practices and deeply disturbed by the mental stress and extreme anxiety this situation has caused me. It feels as though they have essentially jeopardized my employment status. Viseo should seriously reconsider their HR practices and strive for more humane treatment of candidates, including improving their communication skills. If you ever consider interviewing with them, I strongly recommend inquiring about the presence of an active project. Best of luck to all those involved.
