Question 3 of 5
Interview prompt
How would you design an API rate limiter for a distributed service?
Candidate answer
“I would begin with a token bucket and store counters in Redis so every service instance shares the same limit.”
Evidence observed
- Selected an algorithm that handles traffic bursts.
- Identified shared state across service instances.
Adaptive next step
Go deeper on consistency and Redis failure modes.

Turn the gap into focused practice.
One preparation loop
Practice becomes useful when it changes what you do next.
- 01
Add your context
Use your resume, target role, and a pasted job description.
- 02
Practice realistically
Choose a Quick 5 or Full 10 across four interview modes.
- 03
Review the evidence
See what was clear, incomplete, relevant, or technically weak.
- 04
Follow a guided plan
Turn recurring gaps into a realistic weekly preparation sequence.
Feedback you can act on
See the reasoning behind the score.
InterviewForge connects feedback to observable parts of your answer, then gives the next question or practice task a clear purpose.
- Strengths tied to what you actually explained.
- Gaps written as specific, fixable observations.
- A concrete next step instead of generic encouragement.

Candidate answer
“I would begin with a token bucket and store counters in Redis so every service instance shares the same limit.”
Evidence observed
- Selected an algorithm that handles traffic bursts.
- Identified shared state across service instances.
- Failure behavior and consistency need more depth.

Four practice modes
Prepare for the conversation, not a trivia feed.
Every mode asks you to explain, justify, and reflect. Choose five questions for focused practice or ten for a fuller interview.
Behavioral
Evidence-led STAR answers based on work, projects, and decisions.
“Tell me about a time you changed your approach after feedback.”
DSA verbal
Explain algorithms, edge cases, and complexity without a code editor.
“How would you detect a cycle in a directed graph?”
HR
Motivation, goals, role fit, work habits, and clear communication.
“Why does this role fit the direction you want to grow in?”

Candidate trust comes first
Preparation guidance, never a hiring verdict.
Private context
Your resume, job context, and answers remain tied to your account.
Transparent limits
Feedback supports preparation. It does not predict hiring outcomes.
Text always available
Voice input is optional and never blocks the interview experience.
Common questions
Before you begin.
Is InterviewForge a hiring assessment?
No. It is a preparation tool. Scores and feedback help you review an answer, but they are never presented as a hiring decision or prediction.
Which interview formats can I practice?
You can practice HR, technical, behavioral, and DSA verbal interviews. Each session is either a Quick 5 or a Full 10.
Does every interview require a resume or job description?
No. Both are optional context. You can start a general practice session, or add your resume and a pasted job description for more focused questions.
Can I answer without using a microphone?
Yes. InterviewForge is text first. Browser voice input is optional, and editable text remains available throughout the interview.
