I applied through an employee referral. I interviewed at Argonne National Laboratory
Interview
Firstly, phone screens (2 rounds). Then, onsite interviews. The onsite interview lasted for two days. And there were more than 10 rounds. I had to meet all members who were related to the project. Senior members usually asked me non-technical questions. Others' questions were usually coding problems or algorithm design problems.
Interview questions [1]
Question 1
What do you think is the most important thing to the success of a project ?
Phone interview first and followed by a technical onsite interview within 2 weeks, the second one is more technical and people will ask you questions, but not very difficult . After the presentation, you will be showed around the lab and meet a bunch of people
I applied online. I interviewed at Argonne National Laboratory in Oct 2020

No phone interview and it took 3 weeks to get an interview offer after application submission. I had a 1-hour seminar of 40 minutes of research presentation and 20 minutes of Q&A from 10 employees.
