System Design Interview Prep Resources Are Outdated Relative to Actual FAANG Questions
The canonical pool of system design interview questions circulating in prep resources has not kept pace with what major tech companies are actually asking in 2024-2025. Candidates who prepare from top-50 lists encounter completely different questions in real interviews — domain-specific, time-sensitive problems like real-time fraud detection or collaborative sync. The mismatch wastes preparation time and creates false confidence.
Bank fails to provide account statements despite repeated requests
Customers requesting their own account statements are met with phone transfers, disconnections, and no resolution after hours of effort. The inability to access one's own financial records represents both a customer service failure and potential regulatory violation that affects credit card holders seeking documentation.
AT&T Billing Fraud and Phone Return Process Wastes Customers Dozens of Hours
AT&T customers face fraudulent billing disputes and unreturned phone credit investigations that consume 25 or more hours of their time with no resolution. The carrier's negligent handling of returns and billing errors crosses into harassment territory with no accountability mechanism. Consumers need better tools to document, escalate, and resolve telecom disputes without losing weeks of their lives.
Predatory Small Loan Lenders Hide Daily Interest and Balloon Payments in Contracts
Small loan providers charge undisclosed daily interest and include balloon payment terms not mentioned at origination, resulting in borrowers owing multiples of the principal amount. The information asymmetry is deliberate and systematic. Loan contract analysis tools and predatory lending pattern detection would help consumers identify these traps before signing.
Cable and Internet Providers Impose Annual Fee Hikes Far Exceeding Inflation
Long-term cable subscribers face compounding annual price increases on individual fee line items — broadcast TV fees more than doubling over five years — with no proportional service improvement. Customers in areas with limited ISP competition have no leverage to resist these increases and are effectively captive. When competition finally arrives, customers switching away consistently find better pricing elsewhere.
State Farm fights claims, takes 8 months for repairs, then cancels the policy
State Farm resists legitimate claim approvals, takes up to 8 months to complete authorized repairs, then cancels homeowner policies after a claim is filed — systematically punishing customers who use coverage they have paid for.
Home services lead platforms charge high fees for zero viable leads then impose punitive cancellation fees
Angi and similar home services lead platforms charge service businesses $600+/month for lead subscriptions that produce no actionable work, then impose $1,000+ cancellation fees when businesses try to exit. The combination of unverifiable lead quality and financial lock-in traps contractors in subscriptions they cannot afford to keep or leave. This pattern is documented across Angi, HomeAdvisor, and Thumbtack.
T-Mobile Applies Smaller Trade-In Credit Than Documented in Writing Then Charges Return Fee
T-Mobile applied a $13.34/month credit versus the $34.58/month documented in a written chat transcript, then charged a $70 restocking fee when the customer returned the device due to T-Mobile's own billing failure. Multiple escalations over two weeks produced no resolution. Customers with written documentation of promises still face the same stalling pattern.
State Farm PIP coverage leaves own customers undercompensated vs third-party claimants
State Farm pays third-party claimants from at-fault accidents multiples more than it covers for its own policyholders under PIP limits, leaving injured customers with six-figure medical bills despite carrying full coverage.
Ecommerce Owners Juggling Multiple Disconnected Tools
Small ecommerce businesses struggle to manage separate mobile apps, websites, and POS systems, creating operational fragmentation and high setup costs.
AWS/Terraform Workflow Context Switching
Infra engineers constantly switch between AWS Console, Terraform, terminal, and role management with no unified tool
SEO Slow Feedback Loop Discourages Early Founders
Founders abandon SEO prematurely because the early feedback loop is slow and uneven before compounding begins
Founders Build Products Without Validating Real Demand First
Indie developers repeatedly build products nobody needs because finding authentic unmet demand requires monitoring hundreds of community posts manually for genuine pain expressions
Managing AI Models Across Distributed Networked Hardware Is Painful
Deploying and managing AI models across multiple networked machines with varying VRAM/RAM requires manual configuration, lacks hardware-aware model selection, and has no built-in orchestration.
Zendesk Slow With Multiple Tickets and Incomplete Translation
Zendesk slows during busy hours with multiple tickets, impacting SLA. Incomplete page translation forces manual Google Translate use.
Shopify Continues Billing After Store Cancellation with No Clear Exit Path
Shopify charges continue after customers cancel their stores, with the cancellation process looping without confirmation. Customers who never used the platform cannot get charges stopped or receive refunds, suggesting a structural subscription cancellation dark pattern.
Wells Fargo Payment Portal Breaks After Account Transition Making Balance Payment Impossible
When Wells Fargo transitioned a credit card account to another servicer, the payment portal stopped working and began showing account creation errors. Customer service routes between departments that each disconnect the call, making it impossible to pay or close the balance. Customers are left with an outstanding balance and no functional payment mechanism.
Utility Debt Collectors Pursue Consumers for Services They Never Had
Collection agencies pursue and credit-report utility debts for services the consumer never established a relationship with — often due to mistaken identity, fraud, or data errors at the original utility provider. Written disputes are ignored and the invalid debt continues to be reported, leaving consumers with no effective path to correction short of litigation.
PODS Scheduling Entries Are Not Recorded in Their System Despite Phone Confirmations
PODS customers who schedule deliveries and pickups over the phone discover their bookings were never entered into the system, causing critical move-day failures. The disconnect between phone agents and the scheduling backend creates false confirmation loops that leave customers stranded. This systemic data entry failure makes PODS operationally unreliable for time-sensitive moves.
GitHub Actions Runners Accumulate as Orphaned Instances When Process Exits Unexpectedly
GitHub Actions self-hosted runners fail to deregister when the runner process exits or crashes, causing orphaned instances to accumulate in Docker environments with restart policies until the runner limit is hit.
