دي نوعية الاسئلة اللي بسألها في اي مقابلة (مش كل المواضيع بتتغطي بنفس الوزن) بس دي تقدر تعبرها generic guidelines

بالنسبة للمواد تقدر تراجع تغريدة سابقة بالأسفل 👇

1. SQL & Relational Databases (Most Important)
This is the #1 skill for juniors.
• Basic to intermediate SQL: JOINs (all types), GROUP BY, window functions (ROW_NUMBER, RANK, LAG/LEAD), CTEs, subqueries
• Data manipulation: INSERT, UPDATE, DELETE, MERGE
• Indexing basics and query performance
• Aggregations and handling NULLs/duplicates
• Common patterns: deduplication, sessionization, cumulative metrics

2. Python Programming for Data
• Data structures & algorithms (lists, dicts, sets, sorting, hashing)
• Pandas basics (group by, merge, pivot, apply, handling missing data)
• File handling (CSV, JSON, Parquet)
• Functions, list comprehensions, error handling
• Basic scripting & automation

3. ETL/ELT Concepts & Processes
• Difference between ETL and ELT
• Extract, Transform, Load patterns
• Incremental vs full loads
• Idempotency, handling failures, data quality checks
• Scheduling (cron, Airflow basics)

4. Data Modeling & Warehousing Basics
• Star vs Snowflake schema
• Fact vs Dimension tables
• Normalization vs Denormalization
• Slowly Changing Dimensions (Type 1, 2, 3)
• Basic Kimball vs Inmon concepts

5. Version Control & Collaboration
• Git fundamentals (branching, merge, pull requests, rebasing)
• Writing clean commit messages
• Working with GitHub/GitLab

6. Big Data Tools – Lightweight Version
• Apache Spark basics (Spark SQL, DataFrames, not deep tuning)
• Hadoop ecosystem awareness (HDFS, Hive, maybe MapReduce)
• When to use Spark vs Pandas

7. Cloud Platforms
AWS: S3, Glue, Redshift, Lambda, Athena
Azure: Blob Storage, Data Factory, Synapse, Databricks
GCP: GCS, BigQuery, Dataflow, Composer
Focus on storage, basic orchestration, and querying services.

8. Data Quality, Observability & Testing
• Types of data quality issues (freshness, completeness, accuracy)
• Basic testing (schema validation, row count checks, Great Expectations intro)
• Logging and monitoring pipelines

9. Linux/Command Line & Scripting
• Basic bash commands (grep, awk, sed, find, wc)
• Shell scripting basics
• Working with remote servers (SSH, SCP)

10. Behavioral & System Design (Light)
• Walk me through a data pipeline you built
• How do you handle production failures?
• Simple design: “Design a daily sales reporting pipeline”
