If you interview at Google, you’ll be grilled on graph problems and real-world use cases, like Google Maps.

If you interview at Amazon, expect stack/queue questions straight out of their backend systems, think processing millions of print jobs and browser back buttons.

If you interview at Atlassian or Oracle, don’t be surprised if DSA problems are tied to actual product scenarios, like task tracking, caching, and visitor analytics.

Every DSA round cares about:
→ Can you map the right data structure to a real problem?
→ Do you understand WHY Google uses graphs, why Amazon cares about queues, why Microsoft loves sets and tries?

After coaching students and professionals for the last 8+ years and helping them get placed across the board at Google, Amazon, Atlassian, Juspay, Swiggy, and many more companies.

I can tell you with 100% certainty that without mastering these 8 essential data structures and their problems, you won’t be able to clear coding interviews.

Here are the 8 Data Structures You Must Know:

→ 1. Arrays:
Foundation for all DSA. Fast access, easy to use, but slow for inserts/deletes in the middle. Used everywhere, think memory management, and basic storage.

– Learn which pattern to use for which problem
– Map interview keywords to real solutions
– Practice 5–6 Leetcode must-solves per pattern
– Track your progress and build a real interview toolkit }

→ 2. Linked Lists:
Great for inserts/deletes, bad for random access. Useful in implementing queues, stacks, and real-world apps like undo operations.

→ 3. Hash Maps:
Fast key-value lookups, like dictionaries. Power most caching systems and help in solving “find duplicates” or “group by” problems.

→ 4. Stacks & Queues:
Think of your browser history (stack), print jobs (queue), or undo-redo (stack). Interviewers love these for testing order and flow.

→ 5. Trees (including Binary Search Trees):
Used for hierarchical data, searching, sorting, and in system internals. Master BSTs for fast lookups and ordered storage.

→ 6. Tries (Prefix Trees):
Special tree for autocomplete, spell checkers, and prefix matching. Autocomplete in search bars is built on tries.

→ 7. Heaps:
Perfect for getting the min/max element fast. Used in priority queues, scheduling jobs, and heapsort.

→ 8. Graphs:
Most complex but super important. Used in Google Maps, social networks, recommendations, network routing. You need to understand adjacency lists, DFS, BFS, and shortest path algorithms.

Bottom line:
Don’t just practice random Leetcode problems. Master these data structures, and also understand real-world use cases so you don't fall into the trap of tricky questions.

Here is an A-Z list of essential programming terms:

1. Array: A data structure that stores a collection of elements of the same type in contiguous memory locations.

2. Boolean: A data type that represents true or false values.

3. Conditional Statement: A statement that executes different code based on a condition.

4. Debugging: The process of identifying and fixing errors or bugs in a program.

5. Exception: An event that occurs during the execution of a program that disrupts the normal flow of instructions.

6. Function: A block of code that performs a specific task and can be called multiple times in a program.

7. GUI (Graphical User Interface): A visual way for users to interact with a computer program using graphical elements like windows, buttons, and menus.

8. HTML (Hypertext Markup Language): The standard markup language used to create web pages.

9. Integer: A data type that represents whole numbers without any fractional part.

10. JSON (JavaScript Object Notation): A lightweight data interchange format commonly used for transmitting data between a server and a web application.

11. Loop: A programming construct that allows repeating a block of code multiple times.

12. Method: A function that is associated with an object in object-oriented programming.

13. Null: A special value that represents the absence of a value.

14. Object-Oriented Programming (OOP): A programming paradigm based on the concept of "objects" that encapsulate data and behavior.

15. Pointer: A variable that stores the memory address of another variable.

16. Queue: A data structure that follows the First-In-First-Out (FIFO) principle.

17. Recursion: A programming technique where a function calls itself to solve a problem.

18. String: A data type that represents a sequence of characters.

19. Tuple: An ordered collection of elements, similar to an array but immutable.

20. Variable: A named storage location in memory that holds a value.

21. While Loop: A loop that repeatedly executes a block of code as long as a specified condition is true.

Data Analytics Interview Preparation
[Questions with Answers]

How did you get your job?

I was hired after an internship. 
To get the internship, I prepared a bunch for general Python questions (LeetCode etc.) and studied the basics of machine learning (several different algorithms, how they work, when they're useful, metrics 
to measure their performance, how to train them in practice etc.). 

To get the internship I had to pass a technical interview as well as a take-home machine learning (ML) exercise. Then, it was just a question of doing a good job in the internship! 

What are your data related responsibilities in your job? 

I work on our recommendation system. It’s deep learning based. I work on a lot of features to try and 
improve it (reinforcement learning & NLP etc). Since I'm in a start-up, it's also up to our team to put the models we design into production. So, after a phase of research & development and model design, in notebooks, it's time to create a real pipeline, by creating scripts. 
This enables us to define, train, replace, compare and check the status of the models in production. It's basically all in Python, using Keras/TensorFlow, Pandas, Scikit-learn and NumPy. We also do a lot of analysis for the business team to help them compute metrics of interest (related to 
revenue, acquisition etc.). For that, we use an external utility called Metabase. It is is hooked up to our database where we write SQL queries and visualize the results and create dashboards (using 
Tableau/Looker etc). 
I would say my role is quite "full-stack" since we are all involved from the phase of R&D to deployment on our cluster. 

Was it difficult to get this role?

I got hired after an internship. If you come from a scientific background, it's not that hard to transition into data science. All the math is something you will probably have seen already (especially if you're 
doing maths or physics). So, with some preparation and coding practice, you can start applying to internships. 
It took me maybe a month or two of preparation to get some basic ideas of the typical Python data stack (Pandas, Keras, SciKit-learn etc) before I started to send out CVs. Then, if you get an internship, try your best to do the best you can and then maybe you'll be hired after!
