Blockthrough Software Engineer interview questions

Applied from LinkedIn, got an email 2 month later. First got a coding challenge, you have 30 mins to finish, 2 questions, leetcode easy. Then got a phone call with hr as the initial screening, very poor audio quality, no camera on. Without introduction, they jumped straight into some behavior questions. They came very unprepared, didn't know anything about your resume. They don't tell you about their product, expected to know everything about them.
