Like most operating systems, many of the applications are dependent on databases. Since Android runs primarily on mobile platforms with limited memory and storage, it uses a specific database design for this environment. Knowing this and being able to discuss it will demonstrate your qualifications for this role at Doordash and convince the interviewer that you're the candidate for this position.

"Android uses SQLite as its primary database. SQLite is an open-source relational database that is serverless, designed for transactions, and is self-contained. Rather than operate in a client-server model, the SQLite engine is linked directly to the applications. Calls to the library are dynamic and are designed to reduce the latency when accessing the database."
