Vindex interview questions

Applied on Greenhouse, heard back a few weeks later from their HR to schedule a zoom screen followed by interviews with senior leaders and chief execs. It was a slow and unpredictable process (probably 6 weeks total). Interview times were moved and I had to follow up several times to confirm that I was still being evaluated. I had a good discussion with c-suite and followed up twice with HR about a decision but there was no follow-up from them. A pretty unprofessional process...
