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.

About First American Interview Reports
This question was reported by a candidate who interviewed at First American. LeakCode aggregates interview reports from 10+ sources, including 1Point3Acres, Glassdoor, LeetCode Discuss, Blind, Reddit, Indeed, and Nowcoder. Each report is translated where necessary, deduplicated against existing entries, and tagged by company, role, round type, and reporting date.
Use this question as one calibration data point, not a memorization target. Companies typically rotate their question pools every 2-4 months; the exact wording of a 2024 question may differ from what you encounter today. The underlying pattern, difficulty level, and follow-up depth at First American are the higher-signal extractions to take from this report.
For broader preparation context, the First American interview process typically includes a recruiter screen, one or two technical phone screens, and a 4-5 round on-site loop covering coding, system design (at L4+ levels), and behavioral. Reports tagged on LeakCode show the round-by-round distribution and typical difficulty calibration. To browse questions filtered by round type and seniority, use the company hub linked above.
How To Practice This Type of Question
Solve similar problems on LeetCode under timed conditions (25-35 minutes per medium difficulty). The goal is pattern recognition: recognize the underlying technique (sliding window, two-pointer, BFS, memoized recursion, etc.) within 60-90 seconds of reading. Strong candidates verbalize their hypothesis out loud before coding, then iterate based on feedback. Weak candidates dive into implementation immediately, lose time on the wrong approach, and run out of time for follow-ups.
Companies update their question pools every 2-4 months. The exact wording of any given question may have been retired by the time you interview. Focus your prep on the pattern, not the specific problem. The patterns that appear in First American reports consistently are the ones worth investing in; one-off niche problems are not.
During Your First American Round
Apply the standard interview round template: clarify requirements (2-3 minutes), state your approach out loud and confirm direction with the interviewer (3-5 minutes), code with narration (15-25 minutes), test with concrete examples including edge cases (5 minutes), discuss optimization or trade-offs if time permits (5 minutes). This template is universally accepted across FAANG and adjacent companies; deviating from it produces weaker interviewer feedback signal.
The single most predictive failure mode in First American reports tagged "no hire": not asking clarifying questions. Interviewers are explicitly trained to weight this. Strong candidates ask 3-5 clarifying questions even on problems that look obvious; weak candidates dive into code immediately. The clarifying-question check is often the first signal recorded in the interviewer's written notes.
