Interview
I applied online and was given a codesignal to complete. A week after the codesignal, I was invited to the virtual power day which consisted of a technical, behavioral, and case interview. The technical interview was one easy OOP and a medium linked list problem. There were standard behavioral interview questions asked. The case interview involved analyzing some code to find a bug.
All three interviewers were very friendly and made me feel at ease. I had some trouble on the technical interview but made sure to explain my thought process clearly and still got the offer.

The on-site was 3 rounds in any order: 1 behavior and 2 technicals. Highly recommend using LeetCode to practice the technical questions, and brush up on typical behavioral questions such as "Tell me about a project you worked on."

Interview
It was kinda unique, because you also need to prepare for the business-related interview while you're applying for SW engineer position. It doesn't mean you need to have knowledge over the business field. They are trying to observe how my thought process goes in that field. There are also behavior and coding interviews.
