Social threads: focused interview & design prep

- Experienced engineers on X outlined a practical stack: start with easy LeetCode, move to pattern‑based mediums, then timed mocks and system design practice focused on real tradeoffs. - Notable posts include Aman Kumar’s 90‑day roadmap, a 14‑item DSA essentials list, and Shalini Goyal’s one‑page system‑design cheat sheet with caching, sharding and reliability patterns. - Threads emphasise consistency, explaining failure modes at 10×, and resilience patterns (circuit breakers, retries) as interview differentiators for big‑tech loops (x.com/amanaryan23/status/2047671187036365192) (x.com/CryptoTemplar23/status/2047823054902825324) (x.com/goyalshaliniuk/status/2047564684220678580) (x.com/0xlelouch_/status/2047633795634069736) (x.com/patilvishi/status/2047517482106359980)
