Coding interviews test something adjacent to programming ability: solving a problem correctly while narrating your thinking out loud, on a clock, to a stranger watching you work. Plenty of engineers who write good code on the job freeze in that exact format, not because they can't solve the problem, but because they've never practiced solving problems under those specific constraints.
This track treats that as two separate skills that both need direct practice. The first is pattern recognition across data structures and algorithms: arrays, linked lists, trees, graphs, sorting, searching, dynamic programming, so a new problem stops looking new and starts looking like a variation you've seen before. The second is the interview itself: explaining an approach clearly, handling a hint from the interviewer without getting flustered, and staying calm when the first idea doesn't work. System design and behavioral prep round out what's actually evaluated at most companies beyond raw coding ability.
The honest expectation here is that there's no shortcut that guarantees an offer, and anyone who tells you otherwise is selling something. What consistent practice with real feedback does is remove the parts of interview failure that have nothing to do with engineering ability, like freezing up or running out of things to say when you're stuck.
Kodion's AI Interview Simulator runs mock interviews with real-time feedback, so you practice the actual format, explaining your thinking live under time pressure, instead of only solving problems alone in an editor.
Pattern-based practice across the core data structures and algorithms builds transferable recognition rather than memorized solutions to specific problems that won't appear on your actual interview.
Spaced repetition brings earlier patterns, sorting, recursion, graph traversal, back into rotation as you go, so material from week one hasn't faded by the time your interview is scheduled.
System design and behavioral prep are built into the same track instead of treated as afterthoughts, because most real interview loops test both alongside the coding round.
