The whole thing took over a month. It started with a call from HR, then I had two more interviews with the actual team and the hiring manager. There were big gaps between those two. It was kind of weird because when they talked about the job description, they didn't really know it well and couldn't answer my questions about it. The hiring manager also seemed a bit lost on the timeline, as they never knew what it was when I asked at the end of our interviews. They also don't give any feedback, just the automated rejection email, which is a bummer for an entry-level role, but I get it. On the bright side, most of the people seemed nice!
