Was contacted by an HR recruiter several weeks after applying online. Everything moved very quickly after that point, multiple phone interviews per day over the course of 2 days. I spoke with 4 people total - the recruiter, the manager, and 2 leads. The recruiter was very nice and professional, answered many questions up front which is appreciated when you're going to go through hours of interviews. The manager seemed extremely disinterested for the entire interview, so I was surprised when they contacted me for 2 more interviews, dubbed the "final round" by HR. The 2 leads I spoke with last were very nice, they mostly asked about how I work with teammates and managers. Not many questions about content from anybody, which was strange considering I had a lot of experience with it going in. Overall a positive experience, I would recommend applying online.
