A recruiter from Qualtrics called me asking if I would be interested in a career with Qualtrics. After the initial screening interview they setup an appointment for an interview in their office. It was a little more difficult than most interviews, but it was super relaxed and felt more like a conversation than a formal interview. I got an email the next day saying they wanted to move me to the next step in the interview. The final step was a phone interview with one of their top dogs in Dublin, Ireland (Dan Watkins). Similar to the office interviews, Dan was very professional and extremely nice!
The interview process is long and involved, but for a good reason. They want to make sure you're a good fit for the company and that that Qualtrics is a good fit for you. They invest a lot in their employees so they want to make sure they hire the right people from the beginning.
