      Positive experience
      Average interview

      Application

      I applied online. The process took 1+ week. I interviewed at EPAM Systems (Nova Deli) 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.

      No offer
      Negative experience
      Average interview

      Application

      I applied through a recruiter. I interviewed at EPAM Systems (Pune) in May 2026

      Interview

      Total time waste, and highly unprofessional behavior. The process started with initial discussion with TA/HR. Then was first technical round for 1.5 hours which included my experiences so far, project details, Python questions, advanced concepts of AI, ML, Python and Cloud. Then was live coding - design LRU cache; recursive function problem. Then I was scheduled after two weeks for the managerial round. However, in that round also they asked full technical questions and did a live coding again (Que- design singleton class; sliding window problem). This round also lasted 1.5 hours. After 1 week, I was informed that I cleared second round also, and was scheduled for third round (supposed to be managerial). This was rescheduled twice due to managers unavailability and then abruptly cancelled third time. Now that HR is not responding to my calls, emails and messages.

      Interview questions [1]

      Question 1

      1st technical round : design LRU cache; recursive function problem 2nd technical round : design singleton class; sliding window problem; system design for Instagram like app. (asked to use Azure services)

      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.
