Overview

Reviews
Salesforce’s platform serves every customer from a single, metadata-driven, multi-tenant stack. That architecture must stay fast, reliable, and isolated for 150K+ organizations — making the Salesforce System Design Interview a critical round in the onsite loop (expect to set aside about 60 minutes). You might be asked to design a tenant-isolated CRM data layer, a real-time event bus for Platform Events, or a cross-cloud integration hub. Expect follow-ups on capacity sizing, tenant throttling, failure domains, and release safety that echo Salesforce’s #1 engineering value: Trust. This adaptive roadmap mirrors those expectations. You’ll first cement distributed-systems fundamentals (caching, sharding, consensus, rate limiting), then tackle Salesforce-specific challenges like multi-tenant data partitioning, org-level limits, metadata extensibility, and zero-downtime deployments.

WHAT YOU'LL LEARN

A structured playbook for Salesforce’s 45–60-minute System Design interview, covering requirements clarification, ball-park sizing, trade-off analysis, and production validation.
Reusable design patterns for rock-solid tenant isolation — data partitioning, governor limits, and noisy-neighbor mitigation that keep one org from impacting another.
Event-driven and asynchronous workflows built with queues, pub-sub, and idempotent processors for cross-cloud integrations and high-throughput APIs.
Latency-and-trust tactics that blend caching, replication, and encryption to meet tight SLA and availability targets while safeguarding customer data.
Scale-hardening and monitoring practices to throttle hot-tenant fan-out, plan regional failovers, and surface bottlenecks before they reach millions of users.
Straightforward formulas for estimating storage, throughput, and compute — skills interviewers expect on every System Design problem.

"You guys are the gold standard of crash-courses... Narrow enough that it doesn't need years of study or a full blown book to get the gist, but broad enough that an afternoon of Googling doesn't cut it."
