Meta Software Engineer interview questions

It was a phone call with coderpad for coding. Just like how some people say college professors/lecturers who teach class shouldn't have heavy accents, THE SAME THING GOES FOR INTERVIEWERS. I had trouble understand him and it seemed like Facebook didn't give a damn about who they use as their interviewers and just pulled someone out of a hat. The interviewer was nice and knowledgeable about the question he was asking, but that was it. He also called in late, saying he had trouble finding a room that was free. That's super irresponsible, and I feel like Facebook does not dedicate time to improve the interviewing process. I'm glad they don't recruit at my university.
