Resume matching sends resume text to the configured RIGOR backend for transient processing; it is not saved or sent to an external AI provider. AI job analysis and question generation send selected job context to the configured provider.

SYSTEM DESIGN MATH

Staff-level system design interviews require defending exact throughput, bandwidth, RAM working-set, and disk storage numbers. Adjust parameters below to compute real-time capacity requirements:

Peak write load

$$Q_{\mathrm{peak}} = \frac{DAU \times W_{\mathrm{day}}}{86{,}400} \times P$$

Three-year replicated storage

$$S_{\mathrm{3y}} = \frac{DAU \times W_{\mathrm{day}} \times B \times 365 \times 3}{2^{40}} \text{ TiB}$$

CANONICAL HARDWARE & NETWORK LATENCY CONSTANTS (2026 REFERENCE):

OPERATION	LATENCY	DESIGN CONSEQUENCE
L1 / L2 Cache Reference	1 ns / 4 ns	Keep hot loops cache-line aligned (64B); avoid pointer chasing
Mutex Lock / Unlock (Uncontended)	~15–25 ns	Contended atomic CAS across NUMA sockets spikes to >200ns
Main Memory (DDR5 DRAM) Reference	~80–100 ns	Redis in-memory lookup is dominated by network I/O, not RAM
NVMe SSD Random Read (4KB)	~20–70 μs	WAL fsync group-commit is essential for >25k write TPS
Intra-AZ Datacenter RTT (TCP)	~250–500 μs	Sequential N+1 RPCs (50 calls) add 25ms tail latency
Cross-Continent Quorum RTT (US-East ↔ EU)	~75–90 ms	Synchronous Paxos/Raft across regions caps write latency floor
