The application started on LinkedIn, and it took almost two months to get an interview scheduled.

First, there was a phone screening, followed by a technical interview with an engineer, which included a coding exercise.

I solved the problem but was told they wanted better performance (I was likely quite tired during the interview).

Additionally, the engineer interviewing me appeared annoyed with certain questions I asked after the coding portion.

Coding question involving some sorting. I can't remember the exact question.
