I started with an informational interview, then got a formal interview because recruiting is very slow. My phone interview was a formality as I already knew they wanted to interview me but the recruiter asked general skills and background info as well as salary requirements. In person interview was in 2 parts, one on one with the hiring manager and then a panel interview. Nothing too challenging. I appreciated meeting the panel because these would become my peers and people I would be spending a majority of my time with so it was a good opportunity to feel each other out. Follow up with recruiter and securing offer, salary, start date, etc was a hassle. They are not very quick so be patient!
