Some years ago I had an interview from a cybersecurity startup founded by a member of 8200 unit. It was the worst process selection ever: they ask me to perform a demo (with my own hardware, in the nights and weekends) and at least 5 interviews with several VPs and company's key persons. The process seems going well, they made me lot of promises, they told me that we was only two in the final selection step, but suddendly they disappeared and they completely ghosted me. I send several emails to the HR but he did not reply. At the end, I mailed the headhunter that found me on LinkedIn and he told me that they took other decisions. This was very unpolite by them, I wasted lot of private time for nothing.
