I applied online through their website. Heard back after a few weeks and schedule a phone interview which lasted about an hour and asked the usual questions about my skills and interests. They called back a couple weeks later to schedule an in-person interview. At the time I was 9 months pregnant and due any minute, and they were super flexible with scheduling the interview. I had the interview about a week after birth, and they broke up the day for me into 2-hour chunks so that I could go home and feed my baby in between interviews (I lived locally). I thought it was very thoughtful of them. The in-person interview was about 3-4 hours and had mostly the usual questions about my experience, skills, interests, examples of past projects, and some critical thinking "how would you approach this problem?" or "what would you do here?" type of questions. Not too difficult but made you show your thinking skills.

Contacted by recruiter to schedule a virtual interview with a panel. Recruiter was pleasant but very misleading. Everyone on the panel gave a hard sell to work onsite in Pennsylvania. One person was sort of rude in the questions they asked, indicating they disliked me.
