Honest Take — Before You Begin
Let me be honest about the tension at the heart of this module: technical interviews, as currently practiced by most companies, are a flawed evaluation mechanism. They test a narr…
Synthesize all previous modules into interview-ready performance. Master the meta-skills of technical interviews: problem decomposition, pattern recognition, communication, time management, and handling pressure. Build competitive programming speed for stretch problems. As a Rails engineer, your interview advantage is practical experience. When solving a problem, connect it to real systems you have built. "This is similar to how we handled cache invalidation at my last job" or "this reminds me of how Bundler resolves dependencies." Interviewers at companies hiring Rails engineers value practical wisdom alongside algorithmic skill. Years of production experience — real features shipped, real systems kept alive — demonstrate engineering maturity that a fresh CS grad cannot match. The algorithms are the gate — your experience is the differentiator.

Approach: READ: Ch I-VII (interview process), SOLVE: 5-10 problems per data structure/algorithm chapter
Approach: SELECTIVE: solve 3-5 problems per chapter, focus on chapters aligned with your weak areas
Approach: SELECTIVE: use as additional problem source
Work through each item before the checkpoint.
Complete a full mock technical interview (45-60 minutes, 2 problems) with a timer. Record yourself explaining your approach. Review the recording and identify: (1) time spent on u…
