Demonstrate how to use ADO.NET classes to perform database operations including read data in disconnect/connect mode, insert, delete, update, transaction etc. I don't know ADO.NET, so....... Maybe it's not a difficult question.

I presented two case studies with specific follow-up questions about each project. They also asked me about the process I follow, how I collaborate with other workmates, engage with them, and approach issues or disagreements with internal stakeholders.

In an undirected connected graph G = (N, A), an Euler tour is a walk that starts at some node, visits each arc exactly once, and returns to the starting node. A graph is Eulerian if it contains an Euler tour. Show that in an Eulerian graph, the degree of every node is even. Next, show that if every node in a connected graph has an even degree, the graph is Eulerian. Establish the second result by describing an O(m) algorithm for determining whether a graph is Eulerian and, if so, will construct an Euler tour. (Hint: Describe an algorithm that decomposes any graph with only even-degree nodes into a collection of arc-disjoint cycles, and then converts the cycles into an Euler tour.)
