They have a very lengthy interview process, mainly because they want to hire people that a.) fit in well with the team/culture, and b.) have the emotional intelligence to handle all the aspects of the job. There are five "steps" to this interview process:
1.) Application questions
2.) Screening questions (writing exercise) **This includes setting up a test campaign. Many on Glassdoor complained that it was just a secret way for GoFundMe to make money, but that only happens if people contribute. So don't share your campaign - or better yet, set one up for a non-profit/charity you care about and if people donate, so be it!**
3.) Phone interview
4.) On-site interview with leads (which includes another short writing activity). This happens in two parts, with two different groups of leads. In between these interviews, they'll have you shadow an agent, probably so that the two groups of leads have time to connect with each other (is my theory).
5.) Final interview with department head
