'MENTAI' Growth Dashboard that visualizes the growth of interview skills with S-C ranks, score trend graphs, and AI weakness analysis
■ What is MENTAI
MENTAI is an AI interview practice web application specialized for engineer job hunting. When you answer by voice, the AI interviewer immediately returns feedback on 5 axes optimized for engineering roles.
No member registration is required, and you can practice starting from 3 minutes. With the Growth Dashboard, you can now feel your growth through scores and ranks as you repeat practices.
■ Once you know your 'Interview Skill Rank', you'll want to try again
Competitive programming ratings, GitHub Contributions grass, LeetCode streaks. Engineers have a culture of measuring growth with numbers and maintaining motivation by visualizing it.
However, there was no such mechanism in interview practice. No matter how many times you practice, you couldn't tell if you got better than before.
MENTAI's Growth Dashboard brings the gamification mechanisms that engineers are familiar with into interview practice.
■ Features of the Growth Dashboard
[1. S-C Score Rank System]
Ranks S, A, B, and C are given according to the practice results. The overall score and a comparison with the previous week are clear at a glance, creating specific goals such as 'Aiming for A rank next' or 'Score went up by 10 points compared to last week.'
You can feel your interview skills improving with the same sensation as a competitive programming rating or game rank system.
[2. 5-Axis Score Trend Graph]
Scores from 5 perspectives specialized for engineer interviews are graphed as the results of the last 10 practices.
Trends such as 'One perspective is growing, but another is sluggish' can be seen at a glance, making it clear what to focus on next. Details of the evaluation axes will be released soon.
[3. AI Finds Weaknesses and Proposes the Next Practice]
The dashboard automatically extracts the question with the lowest score from past practice results and proposes, 'Let's practice this next.' There is no need to hesitate about what to practice, allowing you to efficiently improve your score.
[4. Performance Analysis by Category]
You can check a list of performance by question category (Technical Tasks, Self-PR, Motivation, Behavioral Traits, Self-Introduction).
You can discover patterns such as 'Good at technical questions but weak at motivation,' allowing you to focus your practice on weak areas.
[5. Share Scores on X]
Simply by pressing the 'Share on X' button from the feedback screen, you can post your score and rank to X (formerly Twitter).
Since the post includes a link to MENTAI, engineers who see the post can start practicing with one click, creating a system where peers can mutually inspire each other. The content of the answers is not shared, so you can share with peace of mind.
MENTAI Growth Dashboard. Overall score, rank, score by skill, trend graph, and AI recommendations can be checked at a glance.
■ Expected Usage
Setting goals: Makes it easier to set specific goals such as 'Raise from B rank to A rank by the end of this week.'
Intensive practice of weaknesses: Repeatedly practice weak questions according to AI recommendations.
Feeling growth: Check the upward-trending score on the graph and maintain motivation.
Sharing with peers: Share the joy of ranking up on X and stimulate fellow job seekers.
■ Future Updates
The Growth Dashboard is scheduled to add more detailed analysis functions in the future according to the accumulation of practice data.
Also, content explaining common pitfalls in engineer interviews based on MENTAI's evaluation axes is scheduled to be released soon.
With free member registration, the Growth Dashboard is available immediately from today.
