I applied online and then emailed back and forth with a recruiter. I needed to fill out a form about my specific experiences. Then I proceeded to the next round, where I had a one-on-one coding challenge.

Things were complex, and the process changed midway with no proper feedback received. I was initially told I could do the coding interview in C, then another recruiter stated C++, and finally, the interviewer himself did not have a specific language

Standard interview. A few questions will probe your tech stack and background. Overall decent if you know your stuff. The interview continues to go deeper into your field of expertise and tests your knowledge.
