Let's look at some key questions to ask during these interviews.

Consider asking: 1) 'Can you explain the CAP theorem and its relevance to NoSQL databases?' 2) 'What are the main types of NoSQL databases and their use cases?' 3) 'How do you handle data consistency in a distributed NoSQL system?' 4) 'Describe your experience with sharding in NoSQL databases.' 5) 'What strategies do you use for NoSQL database performance optimization?' These questions help evaluate the candidate's theoretical knowledge and practical experience with NoSQL technologies.

What's the difference between a NoSQL Database Developer and a NoSQL Data Architect?

NoSQL Database Developers and NoSQL Data Architects are often confused because they both work with NoSQL databases. However, their roles differ significantly in terms of focus and expertise.

A NoSQL Database Developer is primarily concerned with the implementation and maintenance of databases. Typically, these developers are entry to mid-level professionals, skilled in specific NoSQL technologies like MongoDB or Cassandra. They work with programming languages such as JavaScript, Python, and Java, focusing on implementing scalable database solutions and querying databases to meet the requirements of applications.

In contrast, a NoSQL Data Architect operates at a senior level, emphasizing database design and strategy. They possess a broad knowledge of the entire NoSQL ecosystem and use multiple programming languages, including scripting. Their role involves designing data models and workflows, ensuring they align with business goals and support enterprise-level scalability.
