I applied through a recruiter. I interviewed at CG Power Systems USA in Apr 2021
Interview
I was contacted by their recruiter on LinkedIn. I had a phone interview first with 3 math questions. The problems were easy if you remember high school math and basic probability. Then I was scheduled to have a virtual interview with both HR and a senior technical manager. They were very respectful and friendly and the interview process was a very positive experience.
Interview questions [1]
Question 1
In the technical interview, they showed me some seismic data and walked me through the process, and asked me a few questions. I strongly suggest for the second interview to study seismic imaging if you're not in the field.
