1. Talk about the design of a system you are working on. I don't know if this is where I did bad but maybe try to focus on how the system is designed. 2. Fix the given React code and format it so that it looks like what they want. Practice cssing components in a certain way with flex, etc. Flex in their code was one of the things causing problems because of the inline property. 3. Basically they have a diagram of a process that records users checking out a cart and different processes that will send an email to a user if the cart is not checked out for a period of time. Each cart checkout is recorded in a SQL table. Each of these processes are hosted in a single EC2 instance. The four different processes are 1. The vendor checkout cart is written to a table 2. The checkout cart is completed and written to a table. 3. There is another process that will retrieve the cart id's from the vendor for carts that have completed checkouts and update them. 4. There is another process that will check if carts sat too long and an email should be sent to a user. They asked what happens if the EC2 instance fails, if there is a planned DB outage, if the call is rate limited. 4. They explained to me how the data pipeline needs to use the same framework because multiple teams have created their own data pipelines and created their own frameworks, so the validation is not consistent across all pipelines. This interview was a bit different actually because they wanted requirements for internal developers vs for customers. What would the UI look like, etc. 5. Talked to a PM (the one that is suppose to hire me is out on PTO somehow). She asked me about what to do in situations like if the feature could not be implemented, etc. She was great to talk with.
