There's a technical exam prior the interview, so I think you have to do well in their exams to have an in-depth interview with them; however, the interviewers were very chill and would just ask more about your experience in the field you're applying for.

Got interviewed, it was a good one but I am not sure if I made it because they didn't call. I hope they would regardless if I pass or not so applicants like me wouldn't have to keep waiting and be on limbo.
