Interview preparation falls apart when every day becomes a random reaction to anxiety. The goal of a weekly loop is to reduce decision fatigue so your energy goes into problem solving, not constant planning.
The principle
A good prep system should do three things:
- expose you to new material
- reinforce old material before it fades
- simulate the pressure of real explanation
If your current routine only does the first one, you will feel busy without getting noticeably sharper.
A seven-day structure
Day 1: Pattern intake
Pick one DSA pattern or one system design topic. Study one high-quality explanation and take structured notes.
Day 2: Guided repetition
Re-solve two related problems or redraw the same architecture from memory. The goal is recall, not novelty.
Day 3: Timed practice
Run one coding problem under real constraints or do a 35 to 45 minute system design mock for yourself.
Day 4: Review and cleanup
Write down exactly where you hesitated. Those hesitation points are the syllabus for your next cycle.
Day 5: Communication day
Explain one problem or one design out loud. If you cannot narrate the tradeoff clearly, the understanding is still fragile.
Day 6: Mixed set
Alternate between one easier confidence-building task and one stretch problem.
Day 7: Reset
Look over the week, archive notes, and choose the next focus area before Monday arrives.
Score the week on quality, not volume
Track:
- how many problems you could explain cleanly
- how many designs you could reproduce from memory
- which mistakes repeated
Those signals matter more than a raw problem count.

Why this works
The loop intentionally mixes acquisition, repetition, simulation, and review. That is what makes progress compound. Without the review piece, you just keep touching the surface of new topics.
Closing thought
You do not need a heroic prep schedule. You need a repeatable one. A good system should leave you better prepared and less mentally noisy at the end of each week.
