I normally don't write about interviewing experiences on Glassdoor, but this one was so bizarre.

I was contacted by a sourcer, then talked to a recruiter, then spoke with an engineering manager, and finally completed a technical phone screen. During my technical phone screen, I was given a standard (and fairly simple) data structures and algorithms question involving arithmetic operations.

I figured out an optimal solution, wrote it, tested it against all the examples, ran it, and produced the right answer each time. I caught all the edge cases I could think of. The interviewer said, "Your example is complex enough that I believe you've got all the edge cases."

Great. Wonderful. I spent 10 minutes asking questions about the company. The phone screen ended, and I'm fairly confident that I'll be moving forward.

The next day, I got an email from the recruiter saying that they decided to move forward with other candidates.

The only thing I can think of that may have resulted in a 'no decision' was probably culture fit. Maybe I didn't seem excited enough about the company? I guess I'll never know.
