Interview process was very detailed and thorough, but VERY well-managed, transparent, and thoughtful. I was assigned a talent person who was my coordinator throughout - had several behavioral/experience-based interviews with several senior members of the team. If you know Vista, you know that these folks are typically extremely busy, so getting the chance to get facetime with them as just a candidate was impactful.
The interview process culminated in a detailed case study presentation with several of those senior team members. The case study was designed to be close to what my day-to-day role would consist of, and was also delivered in a manner that was mindful of the fact that I am still a full-time employee at another firm while searching for my next opportunity.
All-in-all, I probably met with 8 or 9 senior investment team members, all of whom were extremely personable, genuinely interested, and offered excellent feedback. Compensation expectations were set early and upfront so as not to waste anyone's time, which I also greatly appreciated.
