Meta Software Developer interview questions

The interviewer seemed introverted but laid out the question well. I often asked questions but got less engagement. The first question was a simple array question and I laid out lot of possible solutions. For the second, I asked which way I could go and didn't get any directions and was rejected. I did probe why and they got back saying my solutions was not good enough. I would definitely ask what the recruiter is looking in the solution before proceeding! + What was good is that they don't look into execution on Codility
