iOS · Coding interview prep
You can solve it.
Can you explain it?
The coding prep you do out loud. Speak your reasoning, watch each idea become a card, and iterate from brute-force to optimal — so you stop freezing when it's your turn to talk.

Why it works
The interview tests the talking, not the typing.
No time
Prep in the time you already waste
You can't grind problems around a full-time job. Do one rep between meetings, on the commute, in line for coffee. No laptop, no desk.
The freeze
You solve it — then blank explaining it
You get the answer alone. Then someone watches, asks you to talk through it, and it's gone. Interviewium is where you rehearse the talking.
Burnout
Stop memorizing. Start reasoning.
Sick of drilling patterns you forget by Friday. Talk a brute-force idea into the optimal one and keep the why, not the flashcard.
The mechanic
Speak it. See it. Sharpen it.
Speak your approach
Say your reasoning out loud. Each idea lands as a card in your flow.
See it as code
Every card carries a working snippet you can read back and check.
Iterate to optimal
Refine card by card, from the first brute-force pass to the clean solution.
