I had an initial interview to cover all the basics. Then I was tasked with putting together and giving a ~25 minute presentation. I spoke to the hiring manager after that. I was told I would receive an answer the following week. I emailed them after 2-3 weeks of radio silence. They said they were still reviewing candidates. I never heard anything back from them. While I liked the people I spoke to, the lack of follow-up was unprofessional and unfortunate, especially after completing a semi-lengthy assignment for them
