Meta Network Deployment Engineer, University Grad interview questions

This position was based in Prineville, Oregon which is Facebook's first data center. It was my privilege that I have got a chance to interview at Facebook Inc in January 2019. The entire process was very simple, straight forward and clear, from both HR and all technical people who had taken my interview. I applied through LinkedIn job portal and got a call within 2 weeks. First round was by HR for initial screening, followed by one round of telephonic interview(technical) and leaded to on-site interview. Got a chance to visit data center location. There were in total 5 different rounds on interview, three technical rounds by different engineers such as Hardware Design Engineer, Senior Engineer, and one Software deployment Engineer. All people were extremely friendly through out entire process and questions asked were very specific and detail oriented. As being a university grad, you need to be very clear about all Networking fundamentals! Thats a key part needs to be strong for any university grad position. They won't ask you very deep or mind boggling questions on Networking domain, but all necessary technologies which commonly uses in day to to day networking roles. So make sure you are so sure about their basic operation(how it works) and all related aspect that it covers, specially in terms of Data center operations. Other two rounds among 5 rounds of on-site interview was done by Network Deployment Manager and Senior Network Deployment Manager. They will mostly emphasize on all hypothetical, situational, behavioral questions and scenarios. Your correct answer is secondary thing, but they just want to see what is your thinking process to resolve that specific issue and your thinking process for the same. If your approach is leading in rite direction then you are good to go. HR was very sweet and extremely friendly in nature. She guided me in a very efficient way through out entire process. Her gesture and dealing with me approach was very helpful to make me less nervous to be interviewed for 'The Facebook.' I think this is the key thing of big B companies that the way they handle their candidates and employees.
