I applied through an employee referral. I interviewed at ReliSource (Dhaka) in May 2026
Interview
The interview process was divided into four rounds.
The first round was a written examination conducted at their office. It consisted of three questions:
* An SQL-related question
* A problem-solving question (where C# was the preferred language)
* A JavaScript event handler question
After successfully passing the written exam, I received a call from HR for the first technical interview. During this round, I was asked to solve several problems using C#. The interviewer also asked questions on Object-Oriented Programming (OOP) in C#, SOLID principles, JavaScript, and other related topics.
After clearing the first technical interview, HR invited me to attend a second technical interview. This round was quite similar to the first one, involving additional problem-solving and technical discussions.
Upon passing the second technical interview, I was invited to the final round, which was a combined technical and behavioral interview. In this stage, the interviewer asked various questions about my background. He also discussed the projects listed on my CV and asked detailed questions regarding my contributions, technical decisions, and implementation approaches.
Interview questions [2]
Question 1
In the written examination, there were three questions:
SQL: I was asked to write a query to retrieve the employee with the highest salary from each department.
Problem Solving (BFS): The problem involved a grid consisting of water and land cells. Connected land cells formed an island. I had to determine the total number of islands and find the size of the largest island using a BFS-based approach.
JavaScript: The question focused on event handling, particularly click and transform events. I had to implement a button that increases in size when clicked and changes its color. Once the button reaches a predefined maximum size, it should stop growing and display an alert message instead.
I applied online. The process took 2 months. I interviewed at ReliSource (Dhaka) in Jul 2024
Interview
1. 1st round was a written round where 3 types of questions were given. SQL queries, A coding problem from leetcode and A web based problem on JavaScript.
2. The 2nd round was a technical interview. First part was behavioral, then a coding problem was asked to be solved, then some general questions from inheritance, polymorphism. Finally, they asked dbms related questions which were standard interview questions.
