System Design Interview Partner

Practice coding interviews the right way. Paste the problem — it nudges you toward the solution with hints, only revealing the answer once you've actually tried.

Dropped into unfamiliar code? Paste it. Get the map — what it does, how it flows, and where the bodies are buried — before you touch a thing.

Got dropped into a framework you've never used? Name it and what you know — get the mental model, the core concepts, and the 20% you need to be productive today.

Know where you want to be but not how to get there? Tell it your current spot and the dream role — get the real skills gap and a plan to close it.

An algorithm or concept that won't click? Name it — get it explained with a plain analogy, a walkthrough, the complexity, and when you'd actually use it.

Don't pick a stack you'll fight for years. Describe what you're building and your skills — get a real recommendation with trade-offs, not hype.

Stuck between two technical approaches and second-guessing? Lay them out — get the real trade-offs for YOUR situation and a clear recommendation, not 'it depends.'

Stop prepping each question separately. Tell it the role and a few experiences — get a bank of stories mapped to the questions they'll actually ask.

Walk into the interview already warmed up. It runs a real mock — the actual questions for your role — and tells you where your answers fell flat.

Learn by actually talking. It holds a real conversation at your level, fixes your mistakes gently, and pushes you a little harder each time.

Nobody reads boilerplate. Give it the role and your background — get a cover letter that sounds like you actually want this job, not a template with the company name swapped in.

Mealtime is a battle and they'll only eat beige food. Tell it what they will eat — get meals that sneak in nutrition without a standoff at the table.

Practicing but not improving? Tell it your instrument, level, and time — get a routine that builds real skill instead of just noodling the same five things.

Music theory always sounded like math? Tell it what you want to understand — get it explained in plain language tied to actual songs you know.

Want to switch careers but it feels impossible? Tell it where you are and where you want to go — get the realistic path, the transferable skills, and the gaps to close.

Stop guessing. Give it the symptom and the code — it ranks the likely causes and tells you the one thing to test next. Diagnoses before it touches a fix.

Don't wing the money conversation. This roleplays the negotiation, plays the tough recruiter, and tells you exactly where you left cash on the table.

Want extra income but most 'side hustle' lists are junk? Tell it your skills and time — get realistic ideas that fit you, with how to actually start.

Saw a photo you want to recreate but don't know how? Describe it and your camera — get the settings, lighting, and composition to actually pull it off.

Textbooks teach you to sound stiff. Give it a phrase — get how people actually say it, the slang, and the thing you should never say.

Time off your resume you're dreading explaining? Tell it the situation — get honest, confident language for the resume, cover letter, and the interview question.

Say what you want in plain English, get clean SQL back — plus the gotchas (nulls, dupes, slow joins) you'd only find in production at 2am.

The About page is the hardest thing to write about yourself. Tell it your story — get one that's warm, credible, and doesn't read like a third-person robot.

Attract the right people, not 400 wrong ones. Describe the role — get a job post that's honest, clear on what matters, and doesn't read like every other one.
