Everything our mentors hand to the cohort — interview question banks, cheat sheets, deep-dives — collected here for the engineering community. Filter by course or post type to find what you need.
Cloud Application Integration (CAI) interview questions covering APIs, service connectors, processes, app connections, REST V2 and the real-time / event-driven patterns most candidates skip.
Cloud Data Integration (CDI) interview questions panels ask for IDMC migration roles — with framework-style answers.
Oracle interview questions asked in Informatica interviews — RDBMS fundamentals, DDL / DML / TCL, constraints, joins, views, indexes, analytical functions, set operators and a long set of practical query problems.
AWS interview questions across EC2, S3, VPC, IAM, Lambda, Auto Scaling, ELB, CloudFront and more — with the exact answers panels score on.
A 200+ question bank covering Snowflake architecture, micro-partitions, Time Travel, caching, masking, streams, tasks, dynamic tables, data sharing and dbt-on-Snowflake — the depth panels probe in 2026.
Curated PowerCenter interview questions from real BFSI and pharma hiring loops — covering mappings, transformations, SCD, performance tuning, project architecture, UNIX scripting and Agile workflow.
Foundational Oracle reference — SQL command categories, index types with examples, views (simple, multi-table, inline), and the everyday filter operators (DISTINCT, LIKE, AND/OR/NOT, WHERE, IS NULL, ORDER BY).
A combined reference covering PowerCenter performance tuning, pushdown optimisation and partitioning, version differences (8 → 9 → 10), and how to update a target table without Update Strategy.
Index of Azure Data Engineering reference notes — the Azure Data Factory deep-dive across two parts, plus pointers to interview-question banks for the surrounding Azure / data stack.
A practical UNIX command reference for data and DevOps engineers — file ops, text processing, search, permissions and the daily-driver patterns Informatica engineers actually use.
Every task type available in Informatica IICS / IDMC — Mapping, Synchronization, Masking, Replication, PowerCenter, Dynamic Mapping and Data Transfer — explained with what each one is for.
Foundational reference for data warehousing — BI components, operational vs analytical data, dimensional modelling, star vs snowflake schemas, SCD types, ETL architecture, and design approaches.
A combined reference for the cloud Informatica stack — introduction to IICS / IDMC plus deep dives on the six most-used transformations (Filter, Router, Expression, Joiner, Aggregator, Sorter).
