As a Data Engineer in Germany 🇩🇪 one thing I learned: companies care more about what you can BUILD than what you can list on a CV.
If you’re serious about Data Engineering, build these 5 projects:
Batch ETL Pipeline
Real-time Kafka Pipeline
Spark Data Processing Project
Cloud Data Warehouse
End-to-end Analytics Pipeline
5 strong projects > 50 certificates.
Which attack attempts to insert malicious SQL into an application's database query?
A) DDoS
B) SQL Injection
C) CSRF
D) DNS Spoofing
RAMAYANA – MOVIE REVIEW ⭐⭐⭐⭐½
A visually spectacular retelling of an epic story.
The emotional depth of Ram and Sita’s separation, Hanuman’s devotion, and the intense confrontation with Ravana make this an unforgettable cinematic experience.
The battle sequences are breathtaking, the background score gives goosebumps, and the climax delivers a powerful emotional impact.
Verdict: 4.5/5 — A grand cinematic experience.
#RamayanaMovie
My definition of a successful life has changed.
Earlier:
Big salary + expensive things.
Now:
Healthy parents.
Happy family.
Stable income.
Enough time to actually enjoy all three.
Maybe success becomes simpler as we grow older.
Interviewer:
YOUR AI MODEL SCORES 99% ON RANDOM TEST SPLITS.
On future data: 61%.
What hidden evaluation mistake would you investigate?
I never subscribed, never consented. Who gave them my email address?
Is this Digital India or Digital Surveillance?
A programmer writes 500 lines of code.
AI generates 5,000 lines in seconds.
But who will maintain those 5,000 lines after 5 years?
Interviewer:
YOUR AI AGENT PASSES 99% OF TESTS BUT FAILS WHEN TOOLS RUN IN PARALLEL.
Sequential execution works perfectly.
What hidden problem would you investigate?
A $20 AI subscription can generate thousands of lines of code.
But one production bug can cost $100,000.
Is writing code becoming cheaper than understanding it?
