Unity Backend Developer interview questions

First interview a question about my project, and than an code question to create binary search tree for a list. Second interview with a group manager, free style questions about my projects, work, how I handle error in my project

Got reached out via Linkedin by a lady from the recruitment team, got a phone interview with her not long after, got asked to provide a CV, got promised about a follow up with a technical test a few days after but then nothing. Not even a thank you for sending the CV even though we initially had a nice conversation on LinkedIn. Just heard back after nearly two months that my application will not be considered for the role. It’s quite disappointing and unprofessional unfortunately for such a company like Unity.
