HTTP Status Codes

 

HTTP Status Codes are like messages from the website to your browser, telling you how the request went.

Q1. What is HTTPS?
Answer: HTTPS (HyperText Transfer Protocol Secure) is the secure version of HTTP. It uses SSL/TLS to encrypt communication between the client and server, ensuring confidentiality, integrity, and authentication.

Q2. What is the default port for HTTPS?
Answer: 443.

Q3. Why is HTTPS more secure than HTTP?
Answer: Because it encrypts data in transit, verifies the server's identity using digital certificates, and protects against eavesdropping and tampering.

Q4. What happens if an SSL/TLS certificate is invalid or expired?
Answer: Browsers typically display a security warning, and users should avoid proceeding unless they trust the source.

Q5. Which status code indicates a successful HTTPS request?
Answer: 200 OK (although other 2xx codes like 201 and 204 also indicate successful outcomes depending on the operation).

1. 1xx - Informational : Preliminary status codes indicating the server has received the request and is continuing the process.

2. 2xx - Success : These codes mean the request was successful, showing various outcomes like:
- 200 OK : Everything went smoothly, and the server processed the request successfully.
- 201 Created : A new resource has been successfully created.

3. 3xx - Redirection : Signifying that more action is needed to complete the request, like:
- 301 Moved Permanently : The requested resource has been permanently moved elsewhere.

4. 4xx - Client Error : These codes represent errors caused by the client's request, including:
- 400 Bad Request : The server can't understand the request due to a client error.
- 404 Not Found : The requested resource doesn't exist on the server.

5. 5xx - Server Error : Indicating issues on the server side, such as:
- 500 Internal Server Error : Something unexpected happened on the server, causing an error.

Infosys Interview Pattern

 Infosys Interview Pattern | Automation Testing

🔹 Round 1: Technical Round (Core + Coding)

👉 This is where most candidates get rejected
What I (interviewer) will ask you:
💡 1. Self Introduction (VERY IMPORTANT)
Not your story
Your project + framework + tools + impact
👉 Example structure:
Experience
Project
Tools (Selenium, Java, API, etc.)
What YOU did

💡 2. Selenium + Automation Concepts
Expect questions like:

Difference between find Element() vs find Elements()
Waits (Implicit vs Explicit)
Handling dropdown / alerts / frames
POM (Page Object Model)
How you handle dynamic elements
👉 I will ask:
“Tell me how YOU used it in your project?”

💡 3. Java (Important for Infosys)
OOP concepts (Inheritance, Polymorphism)
Collections (List, Map)
String programs
👉 Example:
Reverse string
Find duplicates
Palindrome

💡 4. Framework Questions (Game Changer)
👉 I WILL ask this: “Explain your framework architecture”
You must explain:
Test layer
Page layer
Base class
Utilities
Reporting
CI/CD

👉 And MOST IMPORTANT:
Flow (how everything works together)

💡 5. API + SQL (Sometimes Asked)
What is API testing
Status codes
Basic SQL query
Join

💡 6. Scenario-Based Questions (VERY IMPORTANT)
👉 I check your thinking:
Test case failing → what will you do?
Script working yesterday but failing today
Element not found → how will you handle

🔹 Round 2: Managerial Round
👉 Here I check your real experience
Questions:
Explain your project in detail
Your role & responsibilities
Challenges faced
How you handled deadlines
How you work in Agile

👉 Tip: Use real examples only (no theory)
🔹 Round 3: HR Round
Expected salary
Notice period
Relocation
Why Infosys?

🔥 What Infosys REALLY Checks
