Interview Preparation Tips
Round 2 - Technical: The second round focused more on system design and APIs. I was asked to explain the difference between PUT and POST in REST APIs, design the database schema of one of my projects, and discuss inheritance and access modifiers (public, private, protected). Git commands were also covered. A scenario-based question was presented: "How would you send an email to a million users, ensuring that if an email fails, the system retries sending it three times? If the retries fail, the system should move on to the next email. Additionally, if the system crashes after sending 1000-2000 emails, how would you ensure that upon restart, it resumes from where it left off without resending emails?"
The HR was friendly, clearly explained the next steps, and provided constructive feedback. Overall, it was a positive interview experience.

Database indexing is a technique to improve the performance of database queries.
Indexing creates a data structure that allows for faster retrieval of data.
Indexes are created on one or more columns of a table.

Use two stacks, one for storing the actual values and the other for storing the minimum values.
When pushing a new value, check if it is smaller than the current minimum value and push it to the minimum stack if it is.
When popping a value, check if it is the current minimum value and pop it from the minimum stack if it is.
To get the minimum val...

LRU cache is a data structure that stores the most recently used items and discards the least recently used items.
LRU stands for Least Recently Used
It has a fixed size and when the cache is full, the least recently used item is removed to make space for a new item
It uses a combination of a doubly linked list and a hash map to achieve O(1) time complexity for both insertion and deletion
Example: A web browser cache that ...
