**General Info**\nStatus: Software Engineer, 10 years of experience\nPosition: E5 at Facebook\nLocation: Menlo Park, CA\nDate: Aug 2019\n\n---\n\n**Technical phone screen (45 min):**\n* [Merge two sorted lists](https://leetcode.com/problems/merge-two-sorted-lists)\n* Follow-up: [Merge K sorted lists](https://leetcode.com/problems/merge-k-sorted-lists)\n\n---\n\n**Onsite**\nFormat: 5 rounds 45 min each\nResult: Offer\n\n**Round 1: [Coding]**\n* Check if a string is a palindrome, you may remove at most one character. [Valid palindrome II](https://leetcode.com/problems/valid-palindrome-ii)\n* In-order binary search tree iterator using controlled recursion. [Binary search tree iterator](https://leetcode.com/problems/binary-search-tree-iterator)\n\n**Round 2: [Behavioral]**\n* At the end we had 15 min to spear, the interviewer asked me a coding question, but I can\'t remember what it was.\n\n**Lunch:**\n* Got to walk around campus and choose where to have lunch.\n\n**Round 3: [Coding]**\n* Given a list of available times (start, end), match the time of the day where most people can attend a meeting. Similar to [Meeting Rooms II](https://leetcode.com/problems/meeting-rooms-ii) (premium)\n \n**Round 4: [System Design]**\n* Given a root domain, create a system to clone the entire site\n\n**Round 5: [Behavioral]**\n* We didn\'t have time to do any coding questions.\n\n---\n\n**Notes**\n\nHow did I apply?\n - I got an email from a Facebook recruiter. I believe they got my contact infro from **LinkedIn**. \n\nThese are some of the behavioral questions I remember: \n- Tell me about a time you received feedback from your supervisor.\n- Tell me about a project that you were not able to complete.\n- Tell me about a project you are the proudest. \n- Tell me about a time you disagree with your manager.\n- Interviewers always ask followup questions, be prepared!\n\nUnless you are applying for a senior position or higher, is **unlikely** that you will get asked system design questions. If you want to know more, there are a few paid and free resources I used:\n- [Grokking the system design interview (paid)](https://www.educative.io/collection/5668639101419520/5649050225344512)\n- [System design premier (free)](https://github.com/donnemartin/system-design-primer)\n- [Tech Dummies - Narendra L (youtube channel)](https://www.youtube.com/channel/UCn1XnDWhsLS5URXTi5wtFTA)\n\n**I want to highlight the [comment made by @Mr-Programmer](https://leetcode.com/discuss/interview-experience/376170/Facebook-or-E5-or-Menlo-Park-or-Aug-2019-Waiting/340059). Coding questions may have been easy to medium dificulty, but while discussing the solution with the interviewer, they wanted me to implement the most optimal solution. For SD, the interviewer interrupted me several times and asked me questions about what I just said**\n\nThe campus is impressive and quite large, make sure you get there with plenty of time.\n\nBefore the interview, the recruiter invitedme to a private webinar hosted every week by Facebook, where they show two mock interviews and talk about strategies to deal with coding and system design questions. They also shared an abundance of resources and videos on how to tackle these interviews. \n\nFacebook has the interviewing process down to a T. It feels very systematic, and it will go quite fast. Once you finish an interview, the door opens, and the next person comes in. Interviewers will ask you if you need water, a snack, or a bathroom break before starting the interview. Make sure you take a bathroom break, even if it is just to wash your hands, to "reset" from the previous interview.\n\nThere is free food everywhere! Don\'t overeat.\n\nSo far, this has been the best interviewing experience; people are prepared and well trained for the interviews with rare exceptions.
