Database Engineer Interview Questions

1,262 database engineer interview questions shared by candidates

The HR questions were standard questions about my overall experience. I talked with several members of the development team. There were not really any specific technical questions, but mostly overall descriptions of what the job would entail. The hiring manager did ask a few technical questions but they were fairly simple. The hiring process has since changed, at least in the group I was in. The process is much more strict and the interviews are much more technical.

We have data that gets loaded once a week. With that in mind we have an application that clients enter search data in to and then SQL has to dynamically build a statement that has 25 different data points/relationships. It works fine, but takes upwards of 30 seconds to return the data to the client. You can not change the existing schema, but you can however add to it. Indexes are already present and optimized on all the different tables. What could you do to make this process much faster??

He started with sharing a simple structure definition and asked how to determine if the contents of the structure could be identified as a B-Tree data structure. He did not work with group I was applying to - no local people to meet with.
