Incredible interview process. It tested your ability to cope with long delays while your potential colleagues performed simple tasks, such as responding to your emails asking about your application status. Visa wants to measure how much patience you have, so they push you to the absolute edge to get an accurate estimate. My first interview was in October of 2014. (Note that I had to include the year.) After waiting weeks for a response, I was invited to an onsite. Weeks later, I received an online coding challenge. Months after that and after many emails from me encouraging the recruiting team to do their job (thereby testing my ability to communicate and work on a team), I finally received a response in April of 2015. Not many companies have the resources for an interview process that is this long. I guess they just want the best.
