starting #30DaysOfAWS today

will share one concept daily —
things that actually matter in real projects

not just exam prep. real stuff. 🧵

follow along 👇

[Mansi 👩‍💻 @MansiCodez]

You don't need 6 months of grinding to get better at interviews.
You need 20 mock interviews and the willingness to feel embarrassed in front of a stranger 19 times.

[Mansi 👩‍💻 @MansiCodez]

The best answer to "tell me about a time you failed" isn't the failure.
It's proving you changed something afterward. Interviewers already know you've failed — they're testing whether you learned.

[Mansi 👩‍💻 @MansiCodez]

AI can write your code.
It still can't explain to your manager why prod went down at 3 AM.
That's still your job. For now.

[Mansi 👩‍💻 @MansiCodez]

Unpopular opinion: "years of experience" means nothing if you've solved the same problem 5 times.
Depth beats tenure every time.

[Mansi 👩‍💻 @MansiCodez]

The HashMap isn't just a DSA topic.
It's the backbone of caching, DB indexes, and half of "easy" LeetCode problems.
Master it once, stop relearning it every interview.

10 books that will do more for your interview prep than 100 random YouTube videos.

Not just DSA — coding rounds, system design, and code quality all covered.

Save this list. You won't need to search for another one. 📚👇

[Mansi 👩‍💻 @MansiCodez]

5 system design concepts that show up in literally every interview:

Load balancing
Caching
Database sharding
Message queues
Rate limiting

Learn these once. Reuse them everywhere.
