🚀 Generative AI Interview Questions with Answers (Part 6)
2️⃣6️⃣ What is an AI API?
👉 An AI API is an interface that allows an application to send requests to an AI model and receive its output without directly managing the model's internal implementation.
📌 Basic flow:

Application → API Request → AI Model → API Response → Application

Examples of applications:
🔹 Chatbots
🔹 Content Generation
🔹 AI Assistants
🔹 Document Processing
🔹 Code Generation
2️⃣7️⃣ What is Model Serving?
👉 Model Serving is the process of making a trained AI model available for inference so applications can send input and receive predictions or generated outputs.
📌 Typical architecture:

User Request
     ↓
API / Server
     ↓
AI Model
     ↓
Prediction
     ↓
Response

💡 Model serving can be implemented using cloud infrastructure, dedicated servers, or edge devices.
2️⃣8️⃣ What is Semantic Search?
👉 Semantic Search finds information based on the meaning and context of a query, rather than relying only on exact keyword matches.
Example:

Query:
"How can I reset my password?"

May retrieve:
"Steps to recover your account credentials"

💡 Semantic search commonly uses embeddings and vector similarity.
2️⃣9️⃣ What is Vector Search?
👉 Vector Search finds items that are similar in vector space by comparing their embeddings.

☕️ Java Interview Questions with Answers (Part 1)
1️⃣ What is Java?
👉 Java is a high-level, object-oriented programming language designed to be portable across different platforms.
Key features:
🔹 Object-Oriented
🔹 Platform Independent
🔹 Secure
🔹 Robust
🔹 Multithreaded
🔹 Automatic Memory Management
📌 Write Once, Run Anywhere is commonly associated with Java's platform independence.
2️⃣ What is JVM?
👉 JVM stands for Java Virtual Machine. It executes Java bytecode and provides the runtime environment required to run Java applications.
📌 Basic flow:

Java Source Code
      ↓
   Compiler
      ↓
  Bytecode
      ↓
     JVM
      ↓
    Output

💡 JVM implementations are platform-specific, which allows the same Java bytecode to run on different operating systems.
3️⃣ What is the Difference Between JDK, JRE, and JVM?
👉 These three components have different roles:
🔹 JVM → Executes Java bytecode
🔹 JRE → JVM + libraries required to run Java applications
🔹 JDK → JRE/runtime components + development tools such as the Java compiler
📌 JDK → Development
📌 JRE → Running applications
📌 JVM → Executing bytecode
4️⃣ What is a Class in Java?
👉 A class is a blueprint for creating objects. It defines data and behavior through fields, methods, constructors, and other members.
Example:

class Student {
    String name;
    int age;

    void display() {
        System.out.println(name + " " + age);
    }
}

💡 Objects are created from classes.
5️⃣ What is an Object in Java?
👉 An object is an instance of a class. It contains state represented by fields and behavior provided by methods.
Example:

class Student {
    String name;

    void display() {
        System.out.println(name);
    }
}

public class Main {
    public static void main(String[] args) {
        Student s = new Student();

        s.name = "Rahul";
        s.display();
    }
}

📌 Class → Blueprint
📌 Object → Instance of the class

🚀 Generative AI Interview Questions with Answers (Part 7)
3️⃣1️⃣ What is LLM Architecture?
👉 LLM architecture refers to the design and components used to build a Large Language Model. Modern LLMs commonly use Transformer-based architectures.
📌 Basic flow:

Input Text
    ↓
Tokenization
    ↓
Token Embeddings
    ↓
Transformer Layers
    ↓
Output Probabilities
    ↓
Generated Text

💡 The exact architecture can differ between models.
3️⃣2️⃣ What is Self-Attention?
👉 Self-Attention allows a model to determine which tokens in an input are most relevant to each other while processing a sequence.
Example:

"The animal didn't cross the road because it was tired."

Attention helps the model consider relationships between words across the sentence.
📌 Self-Attention is a core component of Transformer architectures.
3️⃣3️⃣ What is the Difference Between Encoder and Decoder in Transformers?
👉 Encoder and Decoder are two major Transformer components.
🔹 Encoder → Primarily processes input and builds contextual representations.
🔹 Decoder → Generates output tokens, often using previously generated tokens as context.
Examples:

Encoder → Understanding / Representation
Decoder → Text Generation

💡 Some models use encoder-only architectures, some decoder-only, and some use both.
3️⃣4️⃣ What is Pretraining in LLMs?
👉 Pretraining is the initial large-scale training stage where an LLM learns general language patterns, relationships, and representations from a large dataset.
📌 Basic process:

Large Dataset
      ↓
Tokenization
      ↓
Model Training
      ↓
Learned Parameters
      ↓
Pretrained Model

💡 Pretraining provides the foundation that can later be adapted for specific applications.
3️⃣5️⃣ What is Inference in an LLM?
👉 LLM inference is the process of using a trained model to generate an output for a given input.
Example:

User Prompt
    ↓
Tokenization
    ↓
LLM
    ↓
Next-Token Prediction
    ↓
Generated Response

💡 During inference, the model uses its learned parameters to generate output rather than learning new parameters.
