Backend Engineer Interview Experience - London, United Kingdom
Process
I applied online. The process took four weeks.
It is basically the process as described in their "Demystifying the Backend Engineering" blog post. Initial contact to rejection was almost exactly thirty days, where I was only at stage two of four. I was ghosted about my application for the majority of this time. Be prepared to have to, on the spot in the last ten minutes of a forty-five-minute interview, go from giving a potential improvement to your technical task to expanding it into a full production-ready idea, with complete technical details on how every single part of it will work. Failure to do so will be marked against you, speaking from experience.
Questions
Would you choose to keep an application as a singularly deployed monolith, or turn it into a distributed, horizontally scalable application?
