Typical out of reality interview, asking implementation details about fundamental data structures that you will never implement yourself in practice. Hope they have changed the process since I interviewed there

I applied online and received an online invite to schedule a call with a recruiter. She asked me about myself and went over the resume. In a week I received an invitation for an online Zoom interview. I was asked one question. It was not super hard, however, I did not find the most optimal solution for it. I got an email from the recruiter in a week asking if I am still interested in a position. Later, I got another email with an update that they decided to close this position.
