first was online test , then it was a phone call interview, then a formal interview, and one last one after that. The process was fairly simple, seems like they are hiring a lot of post grad students for this role

A lengthy process but essentially your standard 3 interview process. First one is with a recruiter, second is with the hiring manager, and third is in person with hiring manager and someone else on the team. They do a good job provided as much prep info
