DataVisor Senior Security Engineer interview questions

I went through 6 rounds of interviews. The last one of them was an interview with one of the founders. I invested more than three weeks in the process, I even took sometimes off for the interviews and in the end they did not even have the courtesy of sending me an email letting me know that I did not get the job. They were just silent and reposted the job, I was pretty hurt. I hope this feedback will help Datavisor in the future
