I applied through college or university. The process took 3 days. I interviewed at Micron Technology (New Delhi) in Aug 2021
Interview
It was an on campus hiring. Process was really smooth. There was an online test comprising of Aptitude, Big Data and Cloud Computing Knowledge, SQL Coding and Python Coding. Then there were two interview rounds, one technical and other was technical cum Managerial. I can say the interview would be really easy if you have good grasp on DBMS, Python and basics of Big data. There were also resume related questions in both the rounds.
Interview questions [1]
Question 1
Coding in Python.
Writing SQL Queries.
Questions on Big Data. Basically difference between big data and small data.
Online test consists of dsa questions, sql questions and mcqs.
First round technical interview.It is based on resume. Asked to solve some easy dsa questions, sql queries. Also covered on oop,python.
Next round is a technical+ managerial question with few technical and hr questions
Interview questions [1]
Question 1
Find the second highest salary.
Sort array elements without inbuilt functions. String manipulations
1. DSA (Data Structures & Algorithms)
Goal: Test your problem-solving skills, coding ability, and logical thinking.
Common Topics:
Arrays & Strings → Searching, sorting, sliding window, two pointers
Linked List → Reverse, detect cycle, merge
Stack & Queue → Balanced parentheses, LRU cache
Trees & Graphs → Traversals (DFS/BFS), shortest path
Recursion & Backtracking → N-Queens, permutations
Dynamic Programming → Knapsack, longest common subsequence
Example Question:
“Given an array, find the length of the longest subarray with sum = K.”
“Implement LRU Cache.”
Tip: They check how you think, not just the final answer. Explain your steps.

Question 1
2. DBMS (Database Management System)
Goal: Check your knowledge of databases, queries, and design.
Common Topics:
SQL Queries → SELECT, JOIN, GROUP BY, HAVING
Normalization → 1NF, 2NF, 3NF
Transactions → ACID properties
Indexes → Types, usage, pros/cons
ER Diagrams → Designing schemas
Example Question:
“Write an SQL query to find the 2nd highest salary from the Employee table.”
“Explain the difference between INNER JOIN and LEFT JOIN.”
“What are ACID properties in DBMS?”
Tip: Even if you forget exact SQL syntax, explain the logic clearly.
On campus interview. One technical round with basic coding questions. The HR round focused on applications of different computer science topics like threads etc. The interviewers were freindly and helpful.

Question 1
During the HR round the question asked was give a large text file how to handle it to do the better search operations. No the answer was not using hashmaps but related to using the concepts of threads.
