Applied online, got an email for a 30-min phone call from one of the principals in the practice after 2 months. The first phone call included things like talk about your resume, 60-seconds elevator pitch about your phd research, followed by some questions about my phd research, and some other questions about my previous internship experience. The last 8 minutes was for me to ask questions. I had a lot of questions about the company and the career path there, and he took the time to thoroughly answer them. Since we ran out of time, he said that I can write him emails to ask more questions or we can schedule another call. I ended up just writing him an email with several more questions, and he replied in detail. Then the second 30-min call was a video chat with another member of the team, which was after about 1-2 weeks. The video chat went very well. Interviewer was very friendly and chill, asked about my current projects and also talked about his phd work, spoke honestly about the hard work you have to put in to do well there, and asked if I have work authorization in the end. Then about another 1-2 weeks later, I got an email invite from HR for an on-site full-day formal interview. The full-day interview included one-on-one 30-min chats with 6 people and a 1-hour presentation with a lot of Q&A. They were very interested in my presentation and stopped me at any slide to ask questions. The 30-min chats had some technical questions relating to my coursework, which was the hardest part for me because I haven't looked at coursework in the past 3 years. Vague memories did help. I recommend brushing up some coursework basics relating to your major before the interviews. Lunch was at their office cafeteria. I should have prepared more questions to ask during lunch. In general, having a lot of questions would really ease the conversations. Offer was sent to me in 3 work days. I am impressed by their efficiency and sincerity. Overall, I enjoyed the interview process, which was very efficient starting from the first point of contact. The people I interacted with were very friendly and smart. Although the full-day interview was quite exhausting, they did ask me if I wanted to take a restroom break/coffee break before the presentation and sometimes in between the back-to-back interviews. I thought that was very generous and considerate. The breaks were sufficient for me.
