Last week I was interiviewed for a postition as Software Engineer in facebook.
I know that it is expected to answer two coding questions, actually in the past I reached the on-site interview because I could solve both questions. Usually the first question is something really easy to solve or at least a problem with many approaches to solve it. The second problem is easy/medium level, however this time the initial question was to solve a problem similar to https://leetcode.com/problems/generate-parentheses/, which unfurtunately I couldn't complete within 45 min. I only could start the recursion part. Of course I wasn't invited to the on-site interview this time.
