Explain Retention Policy and Aggregation Type as properties of an in-out parameter. What happens if you get them wrong?
CDIAdvancedTransformations⚑ Common Gap
Answer Guide
Expected: Retention Policy = when the final value is saved, based on task status: On success or warning, On success, On warning, Never (only On success/Never in advanced mode). Aggregation Type = how the value is calculated across rows/partitions: Count, Max, Min. Wrong choices: Retention ‘On success or warning’ can move the saved last-load value past rows that were rejected. Wrong aggregation (e.g. Min on a last-load date) re-reads or skips data.
Strong Answer: Knows to reset the value from the mapping task when backfilling.
Red Flag: Blank on both.

Why It Matters

Your Interview Questions Are Probably Older Than the Product.

IDMC changes with every release. The questions most panels use don't — they live in old documents and in each interviewer's memory. TalentInstinct keeps one bank current for everyone.

New Features Get New Questions

When a release adds or changes capabilities, the bank gains questions that test whether a candidate has really used them.

Answer Guides Stay Accurate

When behaviour changes, the expected answer changes with it — so interviewers never mark a correct, current answer as wrong.

Outdated Questions Are Retired

Questions about deprecated features leave the bank, so candidates are judged on the product as it is today.

The Question Bank

600+ Questions. Exactly the Ones the Role Needs.

Filter by module, section and difficulty, flag the questions candidates most often get wrong, and star favourites for your next round. A few examples:

600+Questions across the three modules, each tagged Foundational, Intermediate or Advanced — and refreshed with every IDMC release.

Answer Guides

Every Interviewer Knows What Good Sounds Like.

Questions come with the answer to expect, what a strong answer adds, and the red flag to listen for — so a mid-level engineer can run a senior-level technical round.

Q

What is the difference between Search API and Search Match API in MDM SaaS?

MDM SaaSIntermediateData Model
Expected

Search API: exact or fuzzy search of existing MDM records — returns matches from the MDM database. Search Match API: runs the match engine against a given input record — returns potential duplicate matches even if the record isn’t in MDM yet. Used in search-before-create to prevent duplicates at ingestion time.

Strong Answer

Ties each API to the search-before-create design: Search Match runs before create, with the match threshold deciding link versus create, while Search API is for lookups of records already persisted.

Red Flag

Treats Search Match API as the same as Search API, or says it can only find records already stored in MDM.

Hiring Workflow

First Call to Final Verdict. One Workspace.

Every candidate goes through the same four steps, and everything your panel learns is kept for the next hire.

01

Pre-Screen

A structured first call that decides who is worth a technical round.

  • Experience by module
  • Notice period, current and expected CTC
  • Must-have checks and a copyable summary
02

Interview

Pick the round and level, then ask from the bank with the answer guide open.

  • Initial Screening, Technical, Managerial, HR
  • Levels matched to seniority
  • Rate each answer live
03

Decide

One scorecard brings the evidence together into a verdict.

  • 12 skill domains vs the candidate's self-rating
  • Strong Hire to Strong Reject
  • PDF, CSV or emailed report
04

Learn

Your panel gets sharper with every hire, not just the bank.

  • AI Summary of recurring gaps
  • Team-submitted questions
  • Shared candidate history
Everything Else Your Panel Needs

Built for How IDMC Teams Actually Hire.

Live Scorecard

Rate answers as you go, score skill domains against the candidate's self-rating, and land on an overall score with a clear verdict.

Shared Candidate History

Every interview your team saves, in one place. Filter by verdict, round and interviewer; export or email the report.

AI Summary

The gaps candidates keep missing, the patterns behind inflated self-ratings, and what to watch for — distilled from past interviews.

Your Own Questions Too

Interviewers add questions that work for them: keep them private, share with the team after admin approval, or propose them for the main bank.

Team Workspace

Invite colleagues by email and they join your workspace when they sign up. Admin and interviewer roles; sign in with email or Google.

Your Data, Kept Separate

Each company's candidates, notes and scores are isolated by database-level access rules, with every action checked on the server.

The Cost of Getting It Wrong

One Wrong IDMC Hire Costs $5,000 – $10,000.

Agency fees, onboarding, lost project velocity and a restarted search. For a specialist IDMC role the number climbs fast — and most of it is avoidable with a better interview.

One bad hire costs 10x more than a year of TalentInstinct.

Fees Paid Twice

Agencies typically charge 8–17% of annual CTC for specialist IT roles — and you pay again when the hire doesn't work out.

3–6 Months Lost

Onboarding, ramp-up, spotting the gap, managing the exit and restarting the search while projects slip.

Stale Questions Miss Real Gaps

A candidate can ace yesterday's questions and still not know today's product. Current questions catch that in the room.

FAQ

Questions We Get Asked.

Anything else? Write to hello@talentinstinct.com.

How often is the question bank updated?

With every IDMC release. New capabilities get new questions, answer guides are revised when behaviour changes, and questions on deprecated features are retired. Updates reach every workspace automatically — there's nothing to install.

How many questions are there, and what do they cover?

More than 600 across CDI, CAI and MDM SaaS, each tagged by section and difficulty (Foundational, Intermediate, Advanced) and backed by answer guides. The scorecard also lets you rate MDM On-Prem, PowerCenter / IDQ, PC2IICS, CDQ, CDGC, MDM integration, REST APIs, communication and best practices.

Can we add our own questions?

Yes. Any interviewer can add questions and keep them private, share them with the team once an admin approves, or propose them for the main bank. You can also suggest edits to existing questions.

Who can see our candidate data?

Only members of your workspace. Each company's candidates, notes and scores are separated by database-level access rules, and every action is checked on the server.

Do we need to install anything?

No. TalentInstinct runs in the browser. Sign in with your work email or Google, invite your interviewers, and they join your workspace when they sign up.

How does billing work?

Plans are billed yearly by invoice and paid by bank transfer or UPI. Monthly billing is available at 20% more. INR prices exclude 18% GST; customers outside India are billed in US dollars.

Are HR and managerial rounds covered?

The scorecard supports Initial Screening, Technical, Managerial and HR rounds today. Dedicated HR and managerial question sets are on the roadmap.
