Interview prep should tell you the truth.
Every interview is stressful for me. I don't speak smoothly under pressure, and I'm rarely sure my skills are where they need to be. Almost everything online about preparing was either useless or so generic it told me nothing about what I was actually missing.
That is how Gapmap started: a way to see which skills are weak and where to dig, instead of guessing.
The rules we hold ourselves to
The rubric comes first
Your answer is graded against criteria written before you ever saw the question. Naming a keyword counts for nothing until you explain it.
Checked before it ships
Every question, rubric, and study note is verified against primary sources. If we can't verify it, it doesn't go up.
No bare numbers
You see which criteria you hit, which you missed, and where you went wrong. A score always comes with its reasons.
Follow-ups when it matters
Near a band boundary the grader asks a follow-up, the way a real interviewer does when they're not sure about you.
How preparation works here
a diagnostic maps what you actually know
materials matched to your gaps
topics close when you prove them
mock interviews, out loud
walk in knowing where you stand
Gapmap was founded by Bohdan Shevchenko, a frontend developer with six years in the industry, after dozens of interviews that ended with "we'll get back to you" and no explanation of what went wrong.
Gapmap is the tool he wished existed. Today we build it around that experience: an honest read of your level, and a clear path to the next one.
What Gapmap won't do
- Inflate scores to keep practice comfortable.
- Pretend one number can predict an interview outcome.
- Sell fear. You already know interviews are stressful; we'd rather fix that.
- Ship content nobody verified.
