As others have said, don't waste your time.
I applied in January, and a recruiter reached out in March. I was still looking for the right fit, so I emailed back on a Wednesday accepting the interview invitation. No answer. I sent a follow up email the following Tuesday, and again no answer. I sent a final email Friday thanking them for their time and interest, and immediately received a response saying they were still interested and wanted to schedule an interview.
Once we connected it seemed as though things were going well. The recruiter detailed the extremely thourough interview process, and moved me forward to a technical quiz. After passing that, she scheduled me with the VP of TAM, for the following week, and sent me a list of videos and resources about Tanium I should learn. I poured hours into their youtube channel, vimeo account, and more, and when I logged onto my interview the guy never even showed. I emailed the recruiter twice more, and then gave up. I like to be well prepared during the interview process, but apparently they don't. Hopefully they don't treat their accounts this poorly!
