Uber Security Engineer interview questions

Technical phone screen was scheduled after initial call with recruiter. Basic security questions on cryptography and application security. 1 coding exercise question. Recruiter responded within two business days saying interview feedback is positive and asked for available dates to schedule second phone screen. I've sent my availability and that's it. No more response. Note to Uber - if you don't wanna hire, just start the interview process. Please avoid this kind of time waste activities in future.

This went through an outside recruiter, then a phone call with the hiring manager. Rapid fire questions one after another. Knew most of the answers. However, hiring manager cursed in every single sentence, repeatedly. Extremely unprofessional. Given all the stuff about UBER in the news, and this manager's cursing, I dont really care if I get hired or not. Never heard back from them either.
