The two technical assignments I worked on were quite reasonable. There are a set of assignments that deal with working w/ a fictitious server in a docker environment. I felt they could do more setting up the docker environment to mimic the problem more accurately. No one in 2021 works with an unfamiliar API that they cannot accurately test against.

1) The take home assignment was to call their API remotely, get an XML file, and load it into their 'model' object. Then you have to parse through the nodes and build a directed graph in Java. I used JGraphT for that tool. Then you have to find the shortest path from one node to another. 2) The 'hackathon' was to download their Camunda 7 server, access a local Restful API, and then use Java Streams to parse the results, and look for for data. Then once you did that, there were 4 more iterations of where they might want stuff, and this would mostly use Lambda in Java, which I also lacked.
