The recruiter who reached out to me raced through reciting the job role and interview process details, never gave me a chance to ask questions, and came across as completely disinterested in me as a candidate. It felt like I was being interviewed just so a legal check box could be ticked.

On an opposite note, the technical phone screen went very well. The interviewer described the problem thoroughly, answered questions well, and generally was someone I could see working with. I ended with a complete solution and answered all the interviewer's follow-up questions, with time to ask about company culture.

I was contacted later through email with a rejection and, specifically, "Per company policy, I'm unable to share any direct feedback" from my recruiter. This came off as very impersonal and reflected poorly on Facebook recruiting.

Given an array of strings and an alphabet, determine if the strings are ordered.
