      Anonymous interview candidate
      New Delhi
      No offer
      Positive experience
      Average interview

      Application

      I applied online. The process took 1+ week. I interviewed at EPAM Systems (New Delhi) in Aug 2023

      Interview

      The interview process is pretty straightforward & transparent - 1st Round - HR round - Half-hour interview, 2nd Round - Technical - 1.5 hour interview, 3rd Round - Manager (Technical) - A senior architect will take 1-hour interview

      Interview questions [1]

      Question 1

      HR round - standard questions on why you want to change, describe your current role, any challenges you faced etc. Technical round - all detailed questions on current project architecture, .net core basics (middlewares, service lifetimes), web API - put vs. post, how do you handle authentication & authorisation, SOLID principles, design patterns - explain which ones you implemented, logical questions, some SQL queries around joins like if you have 2 tables, get the table from the right table & also from the right table even if no matching values present in left. Linq query - Write an example of how to return a complex object. Write a program to calculate the sum of the prices of different flowers passed as a list object using OOPs principles. for example: The user will provide flower quantity, and price, input in the form of a List, (10 lilly, 20 roses). Some questions on Azure, but only basics. Manager (Technical) round - The same questions as above, but in detail on how you implemented everything. Web API - If you have to implement logic for all the APIs and not write redundant code - how will you do? Explain a few design patterns, and repository pattern and how you implemented them in the project.

      Anonymous interview candidate
      No offer
      Positive experience
      Average interview

      Application

      I applied online. I interviewed at EPAM Systems in Dec 2025

      Interview

      The interview process consisted of a single technical round conducted virtually. The interviewer started with basic Java concepts, then moved on to Java 8 (Streams & Collections), followed by a DSA problem, and ended with an SQL query. The discussion was interactive, with follow-up questions on edge cases, time complexity, and approach. Overall, the interview focused more on problem-solving and core fundamentals rather than frameworks

      Interview questions [4]

      Question 1

      Java 8 Streams: Group employees by department and find the highest-paid employee per group.
      Answer question

      Question 2

      DSA: Rearrange a string so that no two adjacent characters are the same. Examples: "aaabbc" → valid rearrangement, "aaab" → not possible.
      Answer question

      Question 3

      SQL: Given orders and order_items tables, write a query to find the top 3 customers who spent the most total amount in the last 3 months.
      Answer question

      Question 4

      Other Topics: Basic Java questions, Collections, and Streams.
