Perhaps the only unprofessional interview experience I've had in my job search. Asked the guy how he was doing, how lockdown was treating him - responses were "good." "It's alright." Then he asked me about my background and interrupted me halfway talking through one of my projects to get on with the technical. Answered the technical with ease.

I was reached out by the recruiter directly through LinkedIn. I was asked one medium and one hard LeetCode-style question, with a few follow-ups. It started with a general introduction.
