Meta Software Developer interview questions

Applied through an employee referral. Failed on a phone screening. The interviewer spoke extremely fast. In addition, there was a strong reverberation (looks like she spoke in a big room) on a line. As a result, I mostly guessed her questions. Even when I asked to repeat a question a few times she didn't change anything in her speech. I've had phone interviews before and they were good enough. But this one was a hell. Besides a few usual questions about previous experience and a reason for changing a job, there were only 2 technical questions, both about complexity of algorithms (O-notations), i.e. quite useless, in other words. I think I answered them correctly (Anyway it makes no sense to remember them). It took about 20 minutes. Overall, it was terrible experience. The worst thing, I failed it not due to lack of some technical skills but just because of communication issues. I have a lot of Java experience (they had open positions for that) and some other modern tools and technologies, as well as I'm opened for learning new technologies. But, unfortunately, I haven't had any chance to demonstrate it on any technical phone interviews. Never again.
