Round 1 Coding Assessment** 1.

Food Distribution *

Problem: You are given an array where the first element N represents the number of sandwiches available, and the remaining elements represent the hunger levels of a row of people (ranging from 0 to 5). Distributing a sandwich to a person decreases their hunger level by 1. The goal is to distribute the sandwiches in a way that minimizes the sum of absolute differences between adjacent pairs of people. *

Example: *

Input: [5, 3, 1, 2, 1] * Action: Distribute sandwiches to achieve hunger levels [1, 1, 1, 1]. *

Output: 0 (Total difference is 0). *

Test Cases: *

Input: 5, 2, 3, 4, 5 $\rightarrow$

Output: 1 *

Input: 3, 2, 1, 0, 4, 1, 0 $\rightarrow$

Output: 4 2.

String Manipulation *

Problem: Given a sentence containing alphabets, numbers, and symbols, write a function to remove all non-alphabetic characters and return the cleaned sentence. *

Example: *

Input: cats AND*Dogs-are Awesome *

Output: cats ANDDogsare Awesome

**

Round 2 System Design** *

Problem: Design a real-estate rental application similar to NoBroker. *

Requirements: The design must account for two distinct workflows: 1.

Owner Workflow: Listing properties and managing inquiries. 2.

Tenant Workflow: Searching for properties and connecting with owners.

**

Round 3 Technical Concepts (Frontend & Backend)** *

Infrastructure: Virtual Private Cloud (VPC) and Container Services. *

Security: Code security best practices. *

Rendering & Performance: Comparison of Server-Side Rendering (SSR) vs. Client-Side Rendering (CSR) and general optimization techniques.

**

Round 4 Security and Scaling** *

Authentication & Authorization: Identity and Access Management (IAM), JSON Web Tokens (JWT), and OAuth workflows. *

DevOps: Deployment strategies. *

Database: Techniques for database scaling.
