Monolith
A Monolith is a traditional way of building software where all parts of the program are combined into one large, unified system. Think of it like a big department store where everything is under one roof, rather than having separate boutique shops spread across a mall. When someone mentions "monolithic application" or "monolithic architecture," they're referring to this all-in-one approach. This is different from newer methods like microservices, where the program is split into smaller, independent pieces. Many established companies still use monoliths because they're simpler to manage when starting out, though some are moving away from them as they grow larger.

Example Interview Questions
Senior Level Questions
Q: How would you decide whether to keep a monolith or break it into smaller pieces?
Expected Answer: A senior developer should discuss business needs, team size, maintenance costs, and scaling requirements. They should explain the trade-offs between keeping a monolith (easier to manage with small teams) versus breaking it up (better for large organizations with multiple teams).
Q: What are the main challenges you've faced with monolithic applications?
Expected Answer: Should discuss real-world experience with issues like deployment complexity, scaling difficulties, and team coordination challenges, along with how they solved these problems.
Mid Level Questions
Q: What are the advantages and disadvantages of a monolithic architecture?
Expected Answer: Should explain benefits like simpler development process and easier debugging, while also noting challenges like harder deployment and scaling limitations.
Q: How would you improve the performance of a monolithic application?
Expected Answer: Should be able to discuss common optimization techniques like caching, database optimization, and code improvements without getting too technical.
Junior Level Questions
Q: Can you explain what a monolithic application is?
Expected Answer: Should be able to explain in simple terms that it's a single-piece application where all features and functions are in one program, using simple examples.
Q: What's the difference between a monolith and microservices?
Expected Answer: Should explain the basic concept that a monolith is one big program while microservices split things into smaller, independent pieces.
