You’ll be interviewed for 45 minutes on each of 5 focal areas:
You will be asked technical questions which require code or algorithms, so be prepared to show your work and be as concise and efficient as possible with your answers. Take hints from the interviewer and be open to other solutions as you go. Study your strongest coding language, algorithms, design patterns, core CS concepts and topics related to the scale of our environment before the interview. Efficiency, structure, syntax, bugs and working code will be the criteria as to how the interviewer will assess your abilities. Testing your code is also important.
- Core concepts - DNS, - web servers, - databases, - security, - storage (RAID types), - troubleshooting. The discussions will start off fairly high level and progressively get more in depth. - Scenario question Something has failed and you need to figure out what’s wrong and how to fix it. - Ask the right questions to gather more information - Problem-solving approach. - Solutions must be geared for Facebook scale - Solutions must be geared for Facebook environment
Study up on the tcp/ip stack and make sure you know it inside and out. Be prepared to have discussions around load balancers, protocols, networking tools, troubleshooting, your favourite networking protocol etc. TCP/IP Illustrated Volume 1 is a useful resource for preparation.
- Design systems/processes for - scale - Facebook’s environment The interviewer may give you a system we currently have in place and have you make suggestions on how it can be improved. He/she may also go down another route and have you design a system completely from scratch on the whiteboard (i.e. design an infrastructure that will handle 10M users for our new XXXXXX system). Questions can range from "How would you scale a service from 1 million to 100 million users" to something general like "Design Facebook." - Systems Design Interview Grokking the System Design Interview <https://www.educative.io/collection/5668639101419520/5649050225344512> Coupon (Worth USD79): d9452425-3d36-4581-9eb7-ffc5369d4dcf GitHub Systems Design example 1.

You will be meeting with one of the Engineering Managers in London, and they will be asking you questions about any significant projects you have worked on to get a feel of your capabilities and how you work on teams and with other groups across an organization. There may also be questions involving how you’ve dealt with conflicts in the past, or what a project you are most proud of is, or what your daily activities are, or what is the toughest feedback you have received. Please be prepared to explain why you are interested in Facebook for your next move. The question “what is your understanding of production engineering” will also likely be asked. Make sure to ask as many questions as you would like of each of the interviewers, they’ll be happy to share as much information about their work here at Facebook as they can. Here are also some practice coding links if you would like to check them out: <http://jsperf.com/fb-interview-question-test/2> <https://www.hackerrank.com/x/?utm%5Fsource=recruit2&utm%5Fcampaign=rebranding> <http://codingforinterviews.com/practice> <http://www.careercup.com/page> FB Code Lab Portal (this link is geared toward university students but some of the sample questions can still be very relevant) To answer the questions “why Facebook” and “what is your understanding of production engineering”, I would also check these links out: Quora (What is PE): <http://www.quora.com/Facebook-Engineering/What-is-it-like-to-be-a-Production-Engineer-at-Facebook> Proygen: <https://code.facebook.com/posts/1503205539947302/introducing-proxygen-facebook-s-c-http-framework/> HBase: <https://code.facebook.com/posts/321111638043166/hydrabase-the-evolution-of-hbase-facebook/> The following link will provide information on current Facebook projects: <https://code.facebook.com/> Tips: Do not guess questions, if you don’t know the answer say so, but do try to discuss a possible answer as opposed to completely giving up. Think your answers out loud, the interviewers will want to get an idea of your thought process and how you approach a problem. Ask clarifying questions if you are unsure of a question. Be enthusiastic and be yourself – the team want to hire someone to work with them so it’s important to show your personality and your interest in the job. Have questions prepared for each focal area and each interviewer. Read the job spec carefully and have questions prepared on the role involved. Best of luck! Christina
A production engineer is someone who is going to be working with the production system. Probably fixing/identifying data issues, network issues, OS issues, security, etc. It usually means you won’t be working on new features all that much.
